Plz answer my question. i will make it brainliest answer. have to answer both questions.

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?
h + 43 = 64
h = 64 + 43
7h + 43 = 64
7h + 7 = 64
what was the hourly fee for the rototiller?
$2
$3
$4
$5
