Question

greg rented a truck for one day. there was a base fee of $19.95 , and there was an additional charge of 82 cents for each mile driven. greg had to pay $178.21 when he returned the truck. for how many miles did he drive the truck

Answer 1

Let x = number of miles, cost per mile = 82 cents = $0.82 

Cost = 19.95 + 0.82*x 

178.21 = 19.95 + 0.82x

0.82x + 19.95 = 178.21

0.82x = 178.21 - 19.95

0.82x = 158.26

x = 158.26/0.82

x = 193

He drove 193 miles.
