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? Let's think first. Chain of thought:
User
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.
Therefore, the answer is 360.
