Question

One customer pays $25 to have 2 pizzas delivered. Another

customer pays $58 for 5 pizzas. How many pizzas are delivered to a customer who
pays $80​

Answer 1

7 pizzas

Step-by-step explanation:

Using the formula for slope (rise/run) we can calculate how much one pizza cost.

`(58-25)/(5-2) =(33)/(3)  = 11` dollars per pizza.

Take the $11 per pizza and divide it by $80 to get 7.2727 pizzas. Since you can not have .2727 of a pizza you round down to 7 pizzas.
