Question

Hamadi and Aisha solve this problem in two different ways. Carlos paid a total of $64 to rent a car. The rental company charges a one-time fee of $20, with an additional charge of $0.50 per mile driven. How many miles did Carlos drive the rental car? Use the drop-down menus to complete the sentences below.

Answer 1

Carlos drove 88 miles in the rental car.

Explanation:

20+.50m=64

-20 -20

.50m=44/.5

m=88

Answer 2

88 miles

Explanation:

Given,

The amount of one time fees = $ 20,

Also, the additional amount per miles = $ 0.50,

If the car is driven x miles,

Then the additional amount for x miles = 0.50x

So, the total charge = 20 + 0.50x

According to the question,

20 + 0.50x = 64

0.50x = 64 - 20

0.50x = 44

`\implies x = (44)/(0.5)=88`

Hence, the car is driven 88 miles.
