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

### Instruction:
John decides to fix a racecar.  It cost $20,000 to fix but he gets a 20% discount.  He wins his first race but only keeps 90% of the money.  The prize is $70,000.  How much money did he make from the car?

### Response:
 Alipata punguzo la 20000 * 0.2 = $<<20000*.2=4000>>4000.
Hivyo ilimgharimu tu 20000 - 4000 = $<<20000-4000=16000>>16,000.
Alibaki na 70,000 * 0.9 = $<<70000*.9=63000>>63,000 kutoka kwenye tuzo.
Hivyo alipata 63,000 - 16,000 = $<<63000-16000=47000>>47,000 kutoka kwenye gari.
