Answer:

30 hours

Step-by-step 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
