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

### Instruction:
John's camera broke so he decided to rent one for 4 weeks.  It was a $5000 camera and the rental fee was 10% of the value per week.  His friend who was there when it broke agreed to pay 40% of the rental fee.  How much did John pay?

### Response:
 Ada ya kukodisha ni 5000*0.1 = $<<5000*.1=500>>500 kwa wiki.
Hivyo iligharimu 500*4 = $<<500*4=2000>>2000.
Rafiki yake alilipa 2000*0.4 = $800.
Hivyo John alilipa 2000-800 = $<<2000-800=1200>>1200.
