Hong rented a truck for one day. There was a base fee of

$17.99

, and there was an additional charge of

75

cents for each mile driven. Hong had to pay

$128.24

when he returned the truck. For how many miles did he drive the truck?

128.24 - 17.99 = 110.25$

110.25 /.75 = 147 miles

First you want to subtract the base fee from the total cost.

128.24-17.99=110.25

Now you want to divide that from the 75 cents.

110.25 divided by 0.75 = 147

The 147 is the total amount of miles driven

Check:

147 divided by 0.75 = 110.25

110.25 + 17.99 = 128.24
