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

### 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:
He got a 20000*.2=$4000 discount
So he spent 20000-4000=$<<20000-4000=16000>>16,000
He kept 70,000*.9=$<<70000*.9=63000>>63,000
So he made 63,000-16,000=$<<63000-16000=47000>>47,000
#### 47000
