Question

Below is a piece of a local pizza place menu where Jacob works.

Large Cheese Pizza $14.85
Large Supreme Pizza $16.90
Cheese Sticks $5.99
Dessert Pizza $6.99

5. Adding additional toppings to a large cheese pizza cost $1.39 per topping. The equation 14.85 + 1.39x = 20 can be used to determine the number of toppings that can be added to a large cheese pizza for a total of $20. Jacob solves the equation and says you can get 4 toppings added if you have $20. Is this reasonable? Justify your response. If the answer is not reasonable, identify the error and then calculate the correct solution.

Answer 1

It is not reasonable because if someone were to add 4 toppings, the price would be $20.41. However, if a person were to add 3 toppings using that equation, the price would $19.02.

Answer 2

It is not reasonable because if someone were to add 4 toppings, the price would be $20.41. However, if a person were to add 3 toppings using that equation, the price would $19.02.
