How and what two simple machines can I use to lift a 1 LB can with 8 quarters ??? PLEASE HELp?

You need to learn what the words mean. There are dozens of ways to lift something and a different machine for each. Quarters of what? The word might mean US coins, or a lot of other things. Whatever it means, you need to spell out what it has to do with lifting a one LB can with simple machines.
