Question

A company that rents a car for $30 per day. Another company will rent the same type of car for $20 per day plus $0.08 for each mile driven. What is the number of miles per day at which the rental fees will be the same?

Answer 1

The amount of miles would be 125 given that they rent for just one day.

Explanation:

In order to find the time in which they are the same, we have to create two equations - one for each company. Using x as the variable for miles driven, we can use the following two equations.

y = .08x + 20

y = 30

Now we can set the two equal to each other.

30 = .08x + 20

10 = .08x

125 = x
