Rapid Rental Car charges $40 rental fee, $15 for gas and $.25 per mile driven. For the same car, Capital Cars charges $45 for rental and gas and $.35 per mile.

Question

 

 

A) For how many miles is the rental cost at both companies the same?

B) What is the cost?

Answer 1

Let it be for x miles.

40+15+0.25x=45+0.35x

10 =0.1x

x=100

 

The mile is 45+0.35*100= 80 or 40+15+0.25*100 =80
