How much do the two used computers cost? ** First find the cost of the two used computers: $200/computer * 2 computers = $<<200*2=400>>400
How much money will James save by picking the cheaper option? ** Then subtract that cost from the cost of the new computer to find the savings: $600 - $400 = $<<600-400=200>>200
