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

### Instruction:
A group of six friends planned to buy a car. The cost of the car is $1700 and they plan to share the cost equally. They had a car wash to help raise funds, which would be taken out of the total cost. The remaining cost would be split between the six friends. At the car wash, they earn $500. However, Brad decided not to join in the purchase of the car. How much more does each friend have to pay now that Brad isn't participating?

### Response:
 Gharama ya gari ni $1700.
Gharama ya kusafisha gari ni $500.
Gharama ya gari ambayo marafiki 6 wanahitaji kugawana ni $1700 - $500 = $<<1700-500=1200>>1200.
Gharama ya gari ambayo marafiki 5 wanahitaji kugawana ni $1200 / 5 = $<<1200/5=240>>240.
Gharama ya gari ambayo marafiki 6 wanahitaji kugawana ni $1200 / 6 = $<<1200/6=200>>200.
Kila rafiki kati ya 5 anahitaji kulipa $240 - $200 = $<<240-200=40>>40 zaidi kuliko wangalipaswa ikiwa Brad angehusika.
