conversations.value: Please show me the solution for: 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?

conversations.value: The weight stack weighed 10*30=300 pounds
  So the added weight made it 300*.2=60 pounds heavier
  So when he lowered the weight it was 300+60=360 pounds
