Stefan’s family rented a rototiller to prepare an area in their backyard for spring planting. The rental company charged an init
ial 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?
The hourly fee is $ 3. Step-by-step explanation: Given, The initial fee = $ 43, Let x be the additional hourly fee ( in dollars ), Thus, the total additional fee for 7 hours = 7x dollars, And, the total fee for 7 hours = Initial fee + Additional fee for 7 hours = ( 43 + 7x ) dollars, According to the question, 43 + 7x = 64 7x = 21 ( Subtracting 43 on both sides ) x = 3 ( Divide both sides by 7 ) Hence, the hourly fee is $ 3.
