Question

Riley earned $38.25 for cleaning the garage. She was paid $4.25 per hour. ​Write​ and solve​ an equation to find how long it took her to clean the garage. ​Include a label in your answer.

Answer 1

It took Riley 9 hours to clean the garage.

Explanation:

With the information provided, you can say that the amount Riley earns for cleaning the garage is equal to the price per hour for the number of hours it takes to clean the garage, which can be express as:

x=4.25y, where:

x is the amount Riley earns for cleaning the garage

y is the number of hours it takes to clean the garage

Now, you can replace x with $38.25 that is the amount that Riley earned and you can solve for y to find how long it took her to clean the garage:

38.25=4.25y

y=38.25/4.25

x=9

According to this, the answer is that it took Riley 9 hours to clean the garage.
