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 the hourly fee for 7 hours, so the equation is 7h + 43 = 64. Subtract 43 from both sides to get 7h = 21, then divide by 7: h = $3 per hour. Choice C gives the correct equation.
