Question

Oceanside Bike Rental Shop charges $12 plus $6 per hour for renting a bike. Sally paid $66 to rent a bike. How many hours did she pay to have the bike checked out?

Answer 1

The dependent variable is the total fee, while the independent variable is the number of hours the equipment is rented. The equation that expresses the total fee in terms of the number of hours rented is y = $25 + $12.50x.

Step-by-step explanation:

The dependent variable in this question is the total fee, while the independent variable is the number of hours the equipment is rented. Let's denote the total fee as 'y' and the number of hours as 'x'.

Since the resort charges an up-front fee of $25 and another fee of $12.50 per hour, the equation that expresses the total fee in terms of the number of hours rented is:

y = $25 + $12.50x
