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?
Let’s work this out in a step by step way to be sure we have the right answer.
47000
He gets a 20000 *.

2 = $4000 discount.

So he paid 20000 - 4000 = $16000.

He kept 70000 *.

9 = $63000.

So he made 63,000 - 16,000 = $47,000.

.

So, the answer is 47000
