Delia spent $250 to rent a boat for 6 hours. The rental company charges a base rate of $150 for the first two 2 hours, and then an hourly rate for each additional hour. How much does each additional hour of boat rental cost?(1 point)

To determine the cost per additional hour of boat rental, we can break down the total cost as follows:

1. The base rate for the first 2 hours is $150.
2. Delia rented the boat for a total of 6 hours, which means she rented it for an additional 4 hours (6 hours - 2 hours = 4 hours).
3. The total cost for the rental was $250.

Now, we can find the cost for the additional 4 hours by subtracting the base rate from the total cost:

\[
\text{Cost for additional hours} = \text{Total cost} - \text{Base rate} = 250 - 150 = 100
\]

Next, we can find the cost per additional hour by dividing the cost for the additional hours by the number of additional hours:

\[
\text{Cost per additional hour} = \frac{\text{Cost for additional hours}}{\text{Number of additional hours}} = \frac{100}{4} = 25
\]

Therefore, each additional hour of boat rental costs **$25**.
