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?
The total cost is the $43 initial fee plus 7 hours at h dollars per hour, so the equation is 43 + 7h = 64. Subtract 43 to get 7h = 21, then divide by 7: h = $3 per hour. The correct choice is $3.
