Answer:
Results are below.
Explanation:
Giving the following information:
The rental for a tandem bike is $18.50 per hour plus $3 for each helmet. Aaron and Zelly have $80 to spend on the bike rental.
First, we need to structure the total cost formula:
Total cost= 18.5x + 3*2
Total cost= 18.5x + 6
x= number of hours
Now, we need to isolate x:
(TC - 6) = 18.5x
x= (TC - 6)/18.5
Finally, for $80:
x= (80 - 6)/18.5
x= 4 hours
