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?
The rental company charges $150 for the first 2 hours, so Delia has 6 - 2 = <<6-2=4>>4 additional hours.
Thus, the additional 4 hours of boat rental costs $250 total rental cost - $150 base rate = $<<250-150=100>>100.
Hence, each additional hour of boat rental costs $100 / 4 additional hours = $<<100/4=25>>25. Answer: \boxed{25}.
To find out how much each additional hour of boat rental costs, we first need to calculate the total cost of Delia's boat rental.
The rental company charges a base rate of $150 for the first two hours. So, we subtract this base rate from the total cost: $250 - $150 = $100.
This remaining amount represents the cost for the additional hours of boat rental (3 hours or more).
Since Delia rented the boat for 6 hours in total, she spent $100 for the additional 4 hours: $100 / 4 = $25 per additional hour.
Therefore, each additional hour of boat rental costs $25.
To find out how much each additional hour of boat rental costs, we first need to calculate the cost for the first 2 hours, which is a flat fee of $150.
So Delia spent $250 - $150 = $100 on the additional hours.
Since she rented the boat for a total of 6 hours, we subtract the initial 2 hours from the total to get the additional hours: 6 hours - 2 hours = 4 hours.
Now, we divide the cost of additional hours by the number of additional hours to find the cost per hour: $100 / 4 hours = $25.
Therefore, each additional hour of boat rental costs $25.
