- The Acme Rent-a-Car agency charges $10.00 per

day and $0.10 per mile to rent a car. The Super

Rent-a-Car agency charges $20.00 per day and

$0.05 per mile to rent a car. If a car is rented for

1 day, at how many miles would the rental charges

of the two agencies be equal?

(A) 50

(B) 100

© 150

(D) 175

(E) 200

Let number of miles be x. Then

10 + 0.1x = 20 + 0.05x

Solve for x.
