Question

Justin rented a truck for one day. There was a base fee of $15.99, and there was an additional charge of 91 cents for each mile driven. Justin had to pay $231.66 when he returned the truck. For how many miles did he drive the truck?

Answer 1

Let m = the number of miles Justin drove the truck

231.66 = 15.99 + .91m

215.67 = .91m

m = 237 miles
