QUESTIONS
To the nearest dollar, what is the current cost of salaries plus benefits at Brownlee School? $________________
If the salary grid were to increase 2%, what would be the cost of salaries and benefits at Brownlee School? $______________
Now, add one year’s experience to Adamache, Brown, Batavia and Hopewell. Make Adamache full time. Using the assumption from the previous question, what would be the cost of salaries and benefits at Brownlee School? $_____________
In what ways would this budgeting system using Excel (or Open Office) improve management’s decision-making capabilities over hand calculations? Consider that this example is for one school only. School Divisions typically have many schools with hundreds of teachers under their employ.
