John injures his shoulder while lifting weights. After the injury, his bench press goes down 80%. After a bit of training, he manages to triple the weight he can bench. If he started with a 500-pound bench press, what is it now?
Let's be accurate as possible and think first.
300
He lost 500 *.

8 = 400 pounds from his bench.

So his bench went to 500 - 400 = 100 pounds.

After training it increased to 100 * 3 = 300 pounds.

.

So, the final answer is 300
