Late fees for the return of a rental item past its deadline are equal to the regular hourly rental rate multiplied by the number of hours past the return deadline, counting only the hours between 9:00 am and 5:00 pm when the shop is open. The rental item does not accrue late fees outside of those hours, though it can be returned to a drop box. If the shop opens 7 days per week, what were the late fees for an item returned late?
- The regular hourly rental rate is $12.
- The item was 54 hours late.
