Alicia is on vacation, and decides to rent a jet ski. She found a ski rental store that rents jet skis for $60 per hour, plus$25 deposit. She also has a coupon for $5 off each hour of jet ski use.

The cost equation is:

C(x) = $25 + $55*x

Step-by-step explanation:

I suppose that you want to find the equation for this situation.

We know that the price is $60 per hour, plus a single deposit of $25.

Then if Alicia rents the ski for x hours, the cost will be:

C(x) = $25 + $60*x

But she also has a discount of $5 per hour, then if she uses the coupon the total cost for x hours will be:

C(x) = $25 +  $60*x - $5*x

C(x) = $25 + $55*x
