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

### Instruction:
Without factoring in the cost of depreciation for his car John made $30,000 doing Uber.  When he finally traded in the car he bought for $18,000 he got $6000 back.  What was his profit from driving Uber?

### Response:
 Alipata $30,000 na alirudishiwa $6,000 kwa jumla ya 30,000+6,000 = $<<30000+6000=36000>>36,000
Alitumia $18,000 kununua gari hivyo faida yake ilikuwa 36,000-18,000 = $<<36000-18000=18000>>18,000
