Answer:
Therefore Jet Skis cost $50 for the rental and Kayaks cost $20.
Step-by-step explanation:
Since they both rent the vehicles at the same price, "x" for jet skis and "y" for kayaks", we can create equations for each store and a system of equations for these, as shown below:
Watersports:
12*x + 9*y = 780
Fun Rentals:
7*x + 11*y = 570
System:
We can isolate "x" on the first equation:
And use it on the second:
We can now use this value to find "x":
Therefore Jet Skis cost $50 for the rental and Kayaks cost $20.
