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? Think carefully first, then make a decision:
He loses 400 * .2 = $80 on the PlayStation. So he sells it for 400 - 80 = $320. The computer cost 700 + 200 = $900. So he was 900 - 320 = $580 out of pocket. So, the answer is 580.
