PLEASE ANSWER!!!The total cost to pay for parking at a state park for the day and rent a paddle boat or shown. (These prices are for BOTH the paddle boats and parking.)

Number of Hours Cost
1. $17
2. $29
3. $41
4. $53

Find the cost to park and the hourly rate to rent a paddle boat.

Answer 1

Parking = $5; Boat rental = $12/h

Explanation:

Let’s rewrite your table.

t/h Cost/$

1 17

2 29

3 41

4 53

The cost goes up $12 each hour. Parking is constant, so that must be the rate for the boat rental.

If we rent for 1 h, the cost is $17.

If $12 is the cost of boat rental, the difference ($17 - $12 = $5) must be the parking fee.

Parking = $5; Boat rental = $12/h

===============

Check: The same formula works for the other times

2 × 12 + 5 = 24 + 5 = 29

3 × 12 + 5 = 36 + 5 = 41

4 × 12 + 5 = 48 + 5 = 53
