Question

Shen rented a truck for one day. There was a base fee $18.95 and there was an additional charge of 83 cents for each mile driven. Shen had to pay $213.17 when he returned the truck. For how many miles did he drive the truck

Answer 1

Let's say Shen drove 2 miles. Shen had to pay the base fee of $18.95 and $.83(2) = $1.66, so Shen paid $20.61 total.

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

18.95 + .83m = $213.17
-18.95 -18.95
.83m = 194.22
.83 .83
m = 234

So, Shen drove 234 miles.

Answer 2

234 miles

Explanation:

Lets set the variable 'n' as the number of miles driven. We can set up the following equation:

18.95 + 0.83n = 213.17

Now, all we have to do is solve it. We can get 0.83n = 194.22, so n = 194.22/0.83 = 234 miles
