(hopefully worth 20 points if not its 10)
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?
