The weight plates cost 200*1.2=$<<200*1.2=240>>240

So his vest cost 250+240=$<<250+240=490>>490

He could get the other vest for 700-100=$<<700-100=600>>600

So he saved 600-490=$<<600-490=110>>110

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?
