Question

Three friends rented a kayak. It cost $4 per hour per person to rent the kayak, plus $2 for each life jacket, and $3 to park the car. It cost $57 in all. How many hours did they spend kayaking? Write an equation and solve.

Answer 1

13 hours

Explanation:

Let y = the total cost

let x = hours

y = 4x + 5 5 = the one time fee of the jacket and the parking

57 = 4x + 5 Subtract 5 from both sides

52 = 4x Divide both sides by 4

13 = x
