Question

You are ordering a pizza and soda for the big game. A deep dish pizza costs $10.25, and a two-liter of soda is $2.00. For each touchdown that the Eagles score on Sunday, Vinny's Pizza lowers the cost by $1.50. How many touchdowns will the Eagles have to score for your bill to come to $4.75? Explain how to solve for the missing value using an equation.

Answer 1

My equation:

10.25 + 2.00 -1.50x = 4.75

12.25 - 1.50x = 4.75
-12.25                -12.25\

-1.50x = -7.50
_____     ___

-1.50        -1.50

        x = 5

Answer 2

I believe the answer is 5.
