Question

Jacob's Boat Rentals charges a one-time fee plus a $5 hourly rate to rent a boat. The cost to rent a boat for 2 hours is $25 and the cost for 3 hours is $30. Which is the one-time fee to rent a boat?

Answer 1

Hi there! The answer is $15

Let the one-time fee be represented by X.
The total cost of hiring a boat for 2 hours is X + $5 per hour × 2 hours = X + $10

The total cost can also be expressed as $25.
Now we can set up an equation.
X + 10 = 25

Subtract 10.
X = 15

Therefore, the one-time fee to rent a boat is $15.

We can check this by plugging in the data for the rent of 3 hours.
$15 + $5 per hour × 3 hours =
$15 + $15 = $30, which is the correct answer.

In short:
The answer is $15
