Question

Emily rented a bike from kaylas bikes. It cost $15 plus $5 per hour.

If Emily paid $50, then she rented the bike for how many hours?

Answer 1

Answer: 7 hours.

Explanation:

The rental price is 15. Add 5 per hour (5x) and the total must be equal to $50

15+5x=50

Solve for x;

`5x=50-15\\5x=35\\x=(35)/(5)\\ x=7`
