Keith rented a truck for one day. There was a base fee of $15,95, and there was an additional charge of 74 cents for each mile driven. Keith had to pay $198.73 when he returned the truck. For how many miles did he drive the truck?

Answer 1

Let x be the number of miles driven.
The cost of the miles driven is 0.74 * x.
The cost of the truck rental is 15.95 + 0.74 * x.
So the equation is 15.95 +0.74 * x = 198.73.
Subtracting 15.95 from both sides we get 0.74 * x = 198.73 - 15.95 = 182.78.
Dividing both sides by 0.74 we get x = 182.78 / 0.74 = <<182.78/0.74=247>>247. Answer: \boxed{247}.
