Answer:

Results are below.

Step-by-step 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
