1. Linear Equations and Ice Cream
What do they have in common?

2. Picture this…..
You go to Friendly’s and order an ice cream Sundae!!! Yummmmmmm
A sundae costs $5 and includes whipped cream.
You want more!!!!
Each additional topping costs
75 cents.

3. 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 Domain
Would these restrictions, if any, place any restrictions on the range
Use your let statements….

4. Let Statements
Let x =
Let y =
Y = mx +b

5. 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

6. After how many toppings will the toppings cost more than just the sundae alone?

7. 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.
