Question

Kyle is renting a jet ski for the day. Below are his two options.

Answer 1

Lets x = # of hours

Powersports Plus: $30 an hour plus a non-refundable deposit of $50.

Write an expression to show how to calculate the cost of Powersports Plus.

30x + 50

Sun & Surf: $20 an hour plus a non-refundable deposit of $80.

Write an expression to show how to calculate the cost of Sun & Surf.

20x + 80

Next, set the 2 expressions equal to each other.

30x + 50 = 20x + 80

Solve:

30x + 50 = 20x + 80

        10x = 30

          x = 3

Two companies cost Kyle the same amount of money at 3 hours
