Question

Bike rental costs $10 plus $7 per hour. Janice paid $52 in total to rent a bike. For how many hours did she rent the bike?

a) 5 hours
b) 6 hours
c) 4 hours
d) 7 hours

Answer 1

Janice rented the bike for 6 hours. Hence, b) is correct.

Step-by-step explanation:

To find out how many hours Janice rented the bike, we can set up an equation based on the given information. Let's denote the number of hours Janice rented the bike as x.

The total cost can be expressed as the sum of the $10 base cost and the additional $7 per hour, so the equation is: 10 + 7x = 52.

To solve for x, we can subtract 10 from both sides of the equation: 7x = 42. Then, divide both sides by 7 to isolate x: x = 6.

Therefore, Janice rented the bike for 6 hours.
