Question

felipe rented truck for one day. there was a base fee of 14.95, and there was an additional charge of 73 cents for every mile driven. felipe had to pay $158.76 when he returned the truck. how many miles did he drive

Answer 1

Let x = number of miles driven

Total cost = fixed cost + variable cost

158.76 = 14.95 +0.73x Now solve. Subtract 14.95 from both sides

158.76 -14.95 = 14.95 +0.73x - 14.95 Simplify

143.81 = 0.73x Divide both sides by 0.73

143.81/0.73 = 0.73x/0.73 Simplify

x= 197 miles driven
