Question

Stefan’s family rented a rototiller to prepare an area in their backyard for spring planting. The rental company charged an initial fee of $43 with an additional fee per hour. If they paid $64 after renting the rototiller for 7 hours, what was the hourly fee?

If h represents the hourly fee, which equation models this problem?



What was the hourly fee for the rototiller?

Answer 1

Let h be the hourly fee. The cost equation is

43 + 7h = 64.

Solve: 7h = 64 − 43 = 21, so h = 21/7 = 3.

The hourly fee was $3 per hour.
