Question

Mathew and Melanie work at their local supermarket located in Brooklyn, New York. They each earn $8 per hour. Mathew worked three hours more than Melanie. If Mathew and Melanie earned a total of $120, how many hours did Melanie work? ​

Answer 1

If they each earn $8 per hour that means Melanie needed to work 15 hours to get $120.

Explanation:

I divided 120 by 8

Answer 2

6 hours

Explanation:

To start this, you must use an equation that models the amount that Mathew and Melanie made based on time. The total amount of money earned by the two of them is 120, and they both work for 8 dollars and hour, and Mathew worked 3 more hours, our equation is 120 = 8x +8(x+3)

We must first solve for x

120 = 8x + 8x +24

-24 -24

96 = 16x

x = 6

x is the amount of hours Melane worked.
