ANSWERS TO QUESTIONS
1. (a) Cost behavior analysis is the study of how specific costs respond to changes in the level of activity within a company.
(b) Cost behavior analysis is important to management in planning business operations and in deciding between alternative courses of action.
2. (a) The activity index identifies the activity that causes changes in the behavior of costs. Once the index is determined, it is possible to classify the behavior of costs in response to changes in activity levels into three categories: variable, fixed, or mixed.
(b) Variable costs may be defined in total or on a per-unit basis. Variable costs in total vary directly and proportionately with changes in the activity level. Variable costs per unit remain the same at every level of activity.
3. Fixed costs remain the same in total regardless of changes in the activity level. In contrast, fixed costs per unit vary inversely with activity. As volume increases, fixed costs per unit decline and vice versa.
4. (a) The relevant range is the range of activity over which a company expects to operate during the year.
(b) Disagree. The behavior of both fixed and variable costs are linear only over a certain range of activity. CVP analysis is based on the assumption that both fixed and variable costs remain linear within the relevant range.
5. This is true. Most companies operate within the relevant range. Within this range, it is possible to establish a linear (straight-line) relationship for both variable and fixed costs. If a relevant range cannot be established, segregation of costs into fixed and variable becomes extremely difficult.
6. Apartment rent is fixed because the cost per month remains the same regardless of how much Adam uses the apartment. Rent on a Hertz rental truck is a mixed cost because the cost usually includes a per day charge (a fixed cost) plus an activity charge based on miles driven (a variable cost).
7. For CVP analysis, mixed costs must be classified into their fixed and variable elements. One approach to the classification of mixed costs is the high-low method.
8. Variable cost per unit is $1.30, or [($165,000 – $100,000) ÷ (90,000 – 40,000)]. At any level of activity, fixed costs are $48,000 per month [$165,000 – (90,000 X $1.30)].
9. No. Only two of the basic components of cost-volume-profit (CVP) analysis, unit selling prices and variable cost per unit, relate to unit data. The other components, volume, total fixed costs, and sales mix, are not based on per-unit amounts.
10. There is no truth in Faye’s statement. Contribution margin is sales less variable costs. It is the revenue that remains to cover fixed costs and to produce income (profit) for the company.
11. Contribution margin is $14 ($40 – $26). The contribution margin ratio is 35% ($14 ÷ $40).

Questions Chapter 5 (Continued)
12. Disagree. Knowledge of the break-even point is useful to management in deciding whether to introduce new product lines, change sales prices on established products, and enter new market areas.
13. $26,000 ÷ 25% = $104,000
14. (a) The break-even point involves the plotting of three lines over the full range of activity: the total revenue line, the total fixed cost line, and the total cost line. The break-even point is deter-mined at the intersection of the total revenue and total cost lines.
(b) The break-even point in units is obtained by drawing a vertical line from the break-even point to the horizontal axis. The break-even point in sales dollars is obtained by drawing a horizontal line from the break-even point to the vertical axis.
15. Margin of safety is the difference between actual or expected sales and sales at the break-even point. 1,250 X $12 = $15,000; $15,000 – $13,200 = $1,800; $1,800 ÷ $15,000 = 12%.
16. At break-even sales, the contribution margin is equal to the fixed costs. The contribution margin ratio is:$180,000$500,000 = 36%
The sales volume to achieve net income of $90,000 is as follows:$180,000+$90,000.36 = $750,000

SOLUTIONS TO BRIEF EXERCISES
BRIEF EXERCISE 5-1
Indirect labor is a variable cost because it increases in total directly and proportionately with the change in the activity level.
Supervisory salaries is a fixed cost because it remains the same in total regard-less of changes in the activity level.
Maintenance is a mixed cost because it increases in total but not proportionately with changes in the activity level.

Re: Assumptions underlying CVP analysis
CVP analysis is a useful tool in analyzing the effects of changes in costs and volume on a company’s profits. However, there are some assumptions which underline CVP analysis. When these assumptions are not valid, the results of CVP analysis may be inaccurate.
The five assumptions are:1. The behavior of both costs and revenues is linear throughout
the relevant range of the activity index.2. All costs can be classified accurately as either fixed or variable.3. Changes in activity are the only factors that affect costs.4. All units produced are sold.5. When more than one type of product is sold, the sales mix will
remain constant.
If you want further explanation of any of these assumptions, please contact me.

PROBLEM 5-3A
(a) Sales were $2,500,000, variable expenses were $1,700,000 (68% of sales), and fixed expenses were $900,000. Therefore, the break-even point in dollars is:$900,000.32 = $2,812,500
(b) 1. The effect of this alternative is to increase the selling price per unit to $6 ($5 X 120%). Total sales become $3,000,000 (500,000 X $6). Thus, the contribution margin ratio changes to 43% [($3,000,000 – $1,700,000) ÷ $3,000,000]. The new break-even point is:$900,000.43 = $2,093,023 (rounded)
2. The effects of this alternative are to change total fixed costs to $810,000 ($900,000 – $90,000) and to change the contribution margin to 27% [($2,500,000 – $1,700,000 – $125,000) ÷ $2,500,000]. The new break-even point is:$810,000.27 = $3,000,000
Alternative 1 is the recommended course of action because it has a lower break-even point.

(a) Current break-even point: $40X = $24X + $270,000(where X = pairs of shoes)

New break-even point: $38X = $24X + ($270,000 + $24,000)$14X = $294,000
X = 21,000 pairs of shoes
(b) Current margin of safety ratio = (20,000 X $40) –(16,875 X $40) (20,000 X $40)

New margin of safety ratio = (24,000 X $38) – (21,000 X $38) (24,000 X $38)

2. Let fixed manufacturing overhead = FMOSales – Variable cost of goods sold – FMO = Gross profit$1,200,000 – ($400,000 + $500,000 + $50,000 + FMO) = $180,000FMO = $70,000
3. Let fixed selling and administrative expenses = FSA
Contribution margin ratio = $180,000 ÷ $1,200,000 = 15%Contribution margin at break-even = $1,300,000 X 15% = $195,000
At break-even, Contribution margin = Fixed costs (FSA + FMO)$195,000 = FSA + $70,000FSA = $125,000
(b) Incremental sales = $1,200,000 X 25% = $300,000Incremental contribution margin = $300,000 X 15% = $45,000
The maximum increased advertising expenditure would be equal to the incremental contribution margin earned on the increased sales, which is $45,000. The other fixed costs are irrelevant to this decision, because they would be incurred whether or not the advertising expen-diture is increased.

PROBLEM 5-3B
(a) Sales were $1,800,000 and variable expenses were $1,170,000, which means contribution margin was $630,000 and CM ratio was 35%. Fixed expenses were $840,000. Therefore, the breakeven point in dollars is:$840,000.35 = $2,400,000
(b) 1. The effect of this alternative is to increase the selling price per unit to $37.50 ($30 X 125%). Total sales become $2,250,000 (60,000 X $37.50). Thus, the contribution margin ratio changes to 48% [($2,250,000 – $1,170,000) ÷ $2,250,000]. The new breakeven point is:$840,000.48 = $1,750,000
2. The effects of this alternative are to change total fixed costs to $660,000 ($840,000 – $180,000) and to change the contribution margin to .30 [($1,800,000 – $1,170,000 – $90,000) ÷ $1,800,000]. The new breakeven point is:$660,000.30 = $2,200,000
3. The effects of this alternative are: (1) variable and fixed cost of goods sold become $675,000 each, (2) total variable costs become $915,000 ($675,000 + $125,000 + $115,000), and (3) total fixed costs are $1,095,000 ($675,000 + $355,000 + $65,000). The new breakeven point is:
X = ($915,000 ÷ $1,800,000)X + $1,095,000 X = .51X + $1,095,000.49X = $1,095,000 X = $2,234,694 (rounded)
Alternative 1 is the recommended course of action using breakeven analysis because it has the lowest breakeven point.

The break-even point in dollars declined from $2,700,000 to $2,356,250. This means that overall the company’s risk has declined because it doesn’t have to generate as much in sales. The two changes actually had opposing effects on the break-even point. By changing to a more commission based approach to compensate its sales staff, the company reduced its fixed costs, and therefore reduced its break-even point. In contrast, the purchase of the new equipment increased the company’s fixed costs (by increasing its equipment depreciation) and reduced its variable direct labor cost, both of which would increase the break-even point.

PROBLEM 5-6B
(a) 1. Let variable selling and administrative expenses = VSASales – Variable cost of goods sold – VSA = Contribution Margin$2,000,000 – ($600,000 + $700,000 + $200,000 + VSA) = $150,000VSA = $350,000
2. Let fixed manufacturing overhead = FMOSales – Variable cost of goods sold – FMO = Gross profit$2,000,000 – ($600,000 + $700,000 + $200,000 + FMO) = $400,000FMO = $100,000
3. Let fixed selling and administrative expenses = FSA
Contribution margin ratio = $150,000 ÷ $2,000,000 = 7.50%Contribution margin at break-even = $2,400,000 X 7.50% = $180,000
At break-even, Contribution margin = Fixed costs (FSA + FMO)$180,000 = FSA + $100,000FSA = $80,000
(b) Incremental sales = $2,000,000 X 15% = $300,000Incremental contribution margin = $300,000 X 7.50% = $22,500
The maximum increased advertising expenditure would be equal to the incremental contribution margin earned on the increased sales, which is $22,500. The other fixed costs are irrelevant to this decision, because they would be incurred whether or not the advertising expenditure is increased.

$16X + $3,026,000 = $20X + $2,052,000 $4X = $974,000
X = 243,500 units
(c) Creative Ideas should employ the capital-intensive manufacturing method if annual sales are expected to exceed 243,500 units and the labor-intensive manufacturing method if annual sales are not expected to exceed 243,500 units. The labor-intensive method is more profitable for sales up to 243,500 units because the fixed costs are lower. The capital-intensive method is more profitable for sales above 243,500 units because its contribution margin is higher.

BYP 5-4 REAL-WORLD FOCUS
(a) Sweeteners and packaging are a variable cost to Coca-Cola because their use is directly proportional to the amount of product produced. If the unit cost of a variable cost item increases, the contribution margin will decline. This will lead to a decline in net income unless the company can increase its selling price, increase the number of units it sells, or reduce other costs.
(b) This description makes the marketing expenditures sound like they are a variable cost, since it suggests that they vary with the amount of units sold. However, unlike variable costs, the relationship of marketing costs is not directly proportional to sales, since other factors also influence units sold. Thus, it is not a pure variable cost. However, it is also not a fixed cost, in that there usually is a relationship between marketing expenditures and sales. For CVP purposes, it might best be handled as a mixed cost, having both a fixed and variable component.
(c) The first measure, gallon shipments of concentrates and syrups, is the activity index, since it best reflects the company’s production and sales activity at the wholesale level, its primary line of business. The second measure, unit cases of finished product, indicates the amount of activity by Coke’s primary customers, the bottlers. Coke also keeps track of this since it provides information about what is happening at the retail level.

BYP 5-5 REAL-WORLD FOCUS
(a) Barnes and Noble has 1,362 stores with a total of 18.8 million square feet. That is a huge investment in fixed costs that have very little value in an e-book environment.
(b) Barnes and Noble’s big advantage (which enabled it to put lots of small independent book sellers out of business), was that each of its superstores had 150,000 books in stock. However, that is no longer as impressive when you consider that booksellers’ websites now give you access to millions of e-book titles which can be downloaded directly to e-readers.
(c) The authors say that the arrival of Apple’s iPad has huge implications for e-books. ITunes has more than 125 million customers. They represent a very wide potential audience for e-books.
(d) Barnes and Nobel earns about $12.50 on a $25 hardcover book. The same book, as an e-book, would sell for $12.99 and Barnes and Noble would earn $3.90. Obviously they can’t afford this decline unless they can dramatically reduce their fixed costs.
(e) Barnes and Noble was one of the first companies to have an e-reader, called the Rocket e-book. However, it abandoned its e-reader in 2003 because sales of e-books had been very low. Four years later Amazon introduced its Kindle e-reader, which has been hugely popular. A second mistake was that Barnes and Noble was very slow to upgrade its website to encourage the sale of e-books. Again, Amazon was more than happy to fill the void.

BYP 5-6 COMMUNICATION ACTIVITY
To: My Roommate
From: Your Roommate
Subject: Cost-Volume-Profit Questions
In response to your request for help, I provide you the following:
(a) The mathematical formula for break-even sales is:
Break-even Sales = Variable Costs + Fixed Costs
Break-even sales in dollars is found by expressing variable costs as a percentage of unit selling price. For example, if the percentage is 70%, the break-even formula becomes X = .70X + Fixed Costs. The answer will be in sales dollars.
Break-even sales in units is found by using unit selling price and unit variable costs in the formula. For example, if the selling price is $300 and variable costs are $210, the break-even formula becomes $300X = $210X + Fixed Costs. The answer will be in sales units.
(b) The formulas for contribution margin per unit and contribution margin ratio differ as shown below:
Unit Selling Price – Unit Variable Costs = Contribution Margin per Unit
Contribution Margin per Unit ÷ Unit Selling Price = Contribution Margin Ratio
You can see that CM per Unit is used in computing the CM ratio.
(c) When contribution margin is used to determine break-even sales, total fixed costs are divided by either the contribution margin ratio or contri-bution margin per unit. Using the CM ratio results in determining the break-even point in dollars. Using CM per unit results in determining the break-even point in units.

(a) The variable gasoline cost of going one mile in the hybrid car would be $0.09 ($3.60/40). The variable gasoline cost of going one mile in the traditional car would be $0.12 ($3.60/30).
(b) The savings per mile of driving the hybrid vehicle would be $0.03 ($0.12 – $0.09).
(c) In order to break even on your investment, you would need to drive 150,000 miles. This is determined by dividing the additional fixed cost of $4,500 by the cost savings per mile of $0.03.
(d) There are many other factors that you would want to consider in your analysis. For example, do the vehicles differ in their expected repair bills, insurance costs, licensing fees, or ultimate resale value. Also, some states and some employers offer rebates for the purchase of hybrid vehicles. In addition, your decision might be influenced by non-financial factors, such as a desire to reduce emissions.
