<human>:  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?
<bot>: How much did John lose from his bench press? ** He lost 500*.8=<<500*.8=400>>400 pounds from his bench
How much did John's bench press go down? ** So his bench went to 500-400=<<500-400=100>>100 pounds
How much did John's bench press go up? ** After training it increased to 100*3=<<100*3=300>>300 pounds
