Answer:
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:
[tex]total = 15.5*3 + 22.8*1\\total = 46.5+22.8\\total = 69.3[/tex]
SO it would cost totally $ 69.3
