What do they have in common?What do they have in common?

Picture this….. You go to Friendly’s and order an ice

cream Sundae!!! YummmmmmmA sundae costs $5 and includes

whipped cream. You want more!!!!Each additional topping costs 75 cents.

Write a Linear Equation to model this situation

Think about what your Dependent Variable would be.

Think about what your Independent Variable would be.

Think about how much you would pay for just the sundae with no additional toppings

Think about any restrictions to the DomainWould these restrictions, if any, place any

restrictions on the range

Use your let statements….

Let Statements Let x =

Let y =

Y = mx +b

Time to graph!!! Use a Table of Values to help

you. • Now think about this scenario…• You only buy a sundae and you

add sprinkles, reece’s pieces, hot fudge, gummy bears, and caramel sauce. How much will your sundae cost, not including tax and tip

After how many toppings will the toppings cost

more than just the sundae alone?

Think of a sundae question?????

• Can you answer your question with your equation, or with your table or with your graph or….

• Do you need a new equation to answer your question.
