Question

Mai earns $7an hour mowing lawns. Her friend Priya earns $8.50 an hour. If Mai started with $15, how many hours will both friends need to work before they have the same amount of money?

Answer 1

30 hours

Explanation:

Given that:

Mai = $7 per hour

Priya = $8.50 per hour

Mai's initial amount = $15

Number of hours when they'll both have the same amount

Let number of hours = x

15 + 7x = 8.50x

15 = 8.50x - 7x

15 = 0.5x

x = 30

they'll both have the same amount in 30 hours
