James catches 3 kinds of fish.  He catches 200 pounds of trout,  50% more pounds of salmon, and twice as much Tuna.  How many pounds of fish did he catch?
He caught 200*.55=100 pounds more salmon than trout
So he caught 200+100=<<200+100=300>>300 pounds of salmon
He caught 300*2=<<300*2=600>>600 pounds of tuna
So in total, he caught 600+300+200=<<600+300+200=1100>>1100 pounds of fish
