Make a table of hours vs. cost:

- 3 h → $8.00
- 4 h → $8.75
- 5 h → $9.50

The cost increases by $0.75 each additional hour (8.75 − 8.00 = 0.75), so the hourly fee is $0.75.

Use one data point to find the rental (initial) fee: rental = total − hourly×hours = 8.00 − 0.75×3 = 8.00 − 2.25 = $5.75.

Answer:
- Hourly fee: $0.75 per hour
- Rental fee: $5.75
