James buys a weight vest for $250. He then buys 200 pounds of weight plates for $1.2 per pound. A 200-pound weight vest would cost $700 but there is a $100 discount. How much does he save with his vest?

How much do the weight plates cost? ** The weight plates cost 200*1.2=$<<200*1.2=240>>240
How much does his vest cost? ** So his vest cost 250+240=$<<250+240=490>>490
How much would the other vest cost? ** He could get the other vest for 700-100=$<<700-100=600>>600
How much did he save? ** So he saved 600-490=$<<600-490=110>>110
