Question

John rented a truck for one day. There was a base fee of
$18.99
, and there was an additional charge of
75
cents for each mile driven. John had to pay
$199.74
when he returned the truck. For how many miles did he drive the truck?

Answer 1

Maria, let's call the mileage m.

 

Let's say John drove 2 miles. He had to pay the base fee of $18.99 and $.75(2) = $1.50, so he paid $20.49 total.

 

We are given his total, though, and asked to find the mileage.

 

18.99 + .75m = 199.74

-18.99                 -18.99

               .75m = 180.75

               .75         .75

                     m = 241

 

So, John drove 241 miles.

 

Hope this helps!
