Dwight spent $250 to rent a jet ski 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, h. The equation 4h + 150 = 250 models Dwight's cost of renting the jet ski. How much does each additional hour of rental cost?

A $20$20
B $25$25
C $30$30
D $45

Answer 1

To find the cost per additional hour of rental, we need to subtract the base rate from the total cost, which is $250.

$250 - $150 = $100

Since Dwight rented the jet ski for 6 hours, we need to find the total cost for the additional 4 hours. We can set up an equation to represent this:

4h + 150 = 100

Subtracting 150 from both sides, we have:

4h = -50

Dividing both sides by 4, we find:

h = -12.5

Since time cannot be negative, we made an error.

The correct equation should be:

4h + 150 = 250

Subtracting 150 from both sides, we have:

4h = 100

Dividing both sides by 4, we find:

h = 25

Therefore, each additional hour of rental costs $25.

The answer is $\boxed{\text{(B)}\ $25}.
