Amanda rented a bike from Ted's Bikes.
It costs $9 for the helmet plus $5.25 per hour.
If Amanda paid about $43.13, how many hours did she rent the bike?

Let h = the number of hours she rented the bike. Write the equation you would use to solve this problem.

Answer 1

`43.13 = 5.25h + 9`

Explanation:

Let's solve this by making an equation.

$9 for the helmet, and $5.25 per hour.

h will stand for hours, C will stand for Amanda's cost.

`C = 5.25h + 9`

Now, substitute in what we learned from the problem.

`43.13 = 5.25h + 9`

This is an equation you can use to solve for the hours.
