1. Why not ask yourself this question? How many pounds of metal can you get from an ore containing 50% metal? I'll bet you can do that in your head. Then look to see how you obtained that number. Then use the same process to work this problem. It's just different numbers. I'll help if you need help and I'll also check your answers.
