The cost to rent a scooter is $15.50 per hour and the cost to rent a watercraft
is $22.80 per hour. use the expression 15.5s + 22.8w to determine how much it
would cost to rent a scooter for 3 hours and a watercraft for 1 hours.

Total cost = $69.3

Step-by-step explanation:

So we have cost of renting a scooter (s) = $15.5/hr

Cost of renting a watercraft (w) = $22.8/hr

The equation

Total cost = 15.5s + 22.8w

So, if the scooter is rented for 3 hours and the watercraft is rented for 1 hour this means:

SO it would cost totally $ 69.3
