Question

Sally needs a minivan. Express Rent-A-Car charges $45 per day plus $0.40 per mile.

Enterprise Rent-A-Car charges $75 per day plus $0.25 per mile. After how many miles will
the price charged by each company be the same?

Answer 1

200 times

Explanation:

45 + 0.4x = 75 + 0.25x

45 + 0.4x - 45 = 75 + 0.25x -45

0.4x = 30 + 0.25x

0.4x - 0.25 x = 30 + 0.25x - 0.25x

0.15x = 30

Multiply by 100 on each side to make it easier.

15x = 3000

x = 200
