Question

Eric made $91 for 7 hours of work.

At the same rate, how many hours would he have to work to make $117?

Answer 1

Answer: 9 hours

It would be 9 hours because you need to divide 91 by 7 which is 13. This gives you the amount of money he makes each hour. Then, divide 117 by 13 which is 9. To check your work you can do 9 times 13 which equals 117.

Answer 2

The correct answer is 9 hours

To find the unit rate, you divide 91 by 7 and get 13. Then divide 117 by 13 and get 9
