Question: There are two babysitters named Mila and Agnes. Mila makes $10 an hour while Agnes makes $15 an hour. Agnes works 8 hours each week. How many hours does Mila need to work to earn as much as Agnes in a month? Think carefully first, then make a decision:
The weekly salary of Agnes is $15 x 8 = $120. So in a month, Agnes earns $120 x 4 = $480. Therefore, Mila needs to work for $480 / $10 = 48 hours to earn as much as Agnes's monthly earnings. So the answer is 48.
