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

### Instruction:
Carol gets a fixed $20 allowance each week. She can also earn $1.5 more dollars each week if she does extra chores. At the end of 10 weeks, she has 425 dollars. How many extra chores did she average each week?

### Response:
 Alipata $42.5 kwa wastani kila wiki kwa sababu 425 / 10 = <<425/10=42.5>>42.5
Alipata $22.5 kila wiki kutokana na kazi za ziada kwa sababu 42.5 - 20 = <<42.5-20=22.5>>22.5
Alifanya kazi za ziada 15 kila wiki kwa sababu 22.5 / 1.5 = <<22.5/1.5=15>>15
