Tom uses 10 weight plates each weighing 30 pounds on an exercise machine.  This exercise machine uses special technology to make the weights 20% heavier on the lowering portion.  How heavy did the weights feel when being lowered?
The weight stack weighed 10*30=<<10*30=300>>300 pounds
So the added weight made it 300*.2=<<300*.2=60>>60 pounds heavier
So when he lowered the weight it was 300+60=<<300+60=360>>360 pounds
