Jim rents a truck. There is a fee of $15.99, there was an additional charge of 79 cents for each mile driven

Jim had to pay $172.41 when he returned the truck. For how many miles did he drive the truck?

First you subtract 172.41 from 15.99 b/c you want to know how many miles he drove without the fee first which I came up with 156.42. So I'm assuming that he drove 198 miles. To check your answer 198 x.79=156.42 + 15.99=172.41
