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

### Instruction:
Greta worked 40 hours and was paid $12 per hour. Her friend Lisa earned $15 per hour at her job. How many hours would Lisa have to work to equal Greta's earnings for 40 hours?

### Response:
 Kwa masaa 40 aliyofanya kazi, Greta alipata jumla ya 40 * 12 = $<<40*12=480>>480.
Ili kujua Lisa anapaswa kufanya kazi kwa masaa mangapi ili apate $480, tunagawanya 480 / 15 = <<480/15=32>>32.
