You were given two options of cars to rent to drive to California with renting prices listed below.

Question

The Honda Civic would cost $15 plus $0.50 per mile driven.
The Ford Focus would cost $25 plus $0.25 per mile driven.
Create an inequality to represent any number of miles for which the Honda Civic would be the better renting option. Explain what your inequality means.

I know that anything greater than 40 miles is a better deal for the Honda Civic, but how do i structure the inequality?

Answer 1

Honda: y = 15 + .50x
Ford: y = 25 + .25x

15 + .50x = 25 + .25x
Subtract 15 from both sides:
.50x = 10 + .25x
Subtract .25x from both sides:
.25x = 10
Divide by .25, gives you x = 40

Answer 2

Correct
