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

### Instruction:
 Bila kuzingatia gharama ya kupungua kwa thamani ya gari yake, John alipata $30,000 kwa kufanya Uber. Wakati alipouza gari alilolinunua kwa $18,000, alipata $6,000 kama fedha ya kurudishiwa. Ni faida gani aliyopata kwa kuendesha 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
