To find the cost for each additional hour of boat rental, we can break down the total cost.
- The base rate for the first 2 hours is $150.
- Delia rented the boat for 6 hours, which means she rented it for 4 additional hours (6 hours - 2 hours = 4 hours).
- The total cost for the rental was $250.
Now, we can calculate the cost for the 4 additional hours:
Total cost - Base rate = Cost for additional hours $250 - $150 = $100
Now, we divide the cost for the additional hours by the number of additional hours:
Cost per additional hour = Cost for additional hours ÷ Number of additional hours Cost per additional hour = $100 ÷ 4 hours = $25
Thus, each additional hour of boat rental costs $25.
