Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
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?

### Response:
In a week, Agnes earns $15 x 8 = $<<15*8=120>>120.
So in a month, Agnes earns $120 x 4 = $<<120*4=480>>480.
Therefore, Mila needs to work for $480 / $10 = 48 hours to earn as much as Agnes's monthly earnings.
