Question

Patrick is a great babysitter. He makes $9 an hour. Lila is an even better babysitter. She makes $12 an hour. Lila works 6 hours each week. How many hours does Patrick need to work in order to earn as much money as Lila earns in a week?

Answer 1

8 hours

Explanation:

We know that since Lila earns $12/hr and works 6 hr/week, she earned 72 since 12 * 6 = 72.

We can let the amount Patrick earns each week represent 9h, where h is the amount of hours he works.

We can solve for h by setting Patrick's equation equal to 72, which is Lila's earnings:

`9h=72\\h=8\\\\9(8)=72\\12(6)=72`
