John decided to sell his PlayStation to buy a new computer.  The computer's cost was $700 and the accessories cost was $200.  The PlayStation was worth $400 but he sold it for 20% less than its value.  How much money came out of his pocket?
How much did John lose on the PlayStation? ** He loses 400*.2=$<<400*.2=80>>80 on the PlayStation
How much did John sell the PlayStation for? ** So he sells it for 400-80=$<<400-80=320>>320
How much did the computer cost? ** The computer cost 700+200=$<<700+200=900>>900
How much money came out of his pocket? ** So he was 900-320=$<<900-320=580>>580 out of pocket
