can some one help me out I am not a baker or maybe I should.

If I was cooking a pie for 10 people how many pounds of apples will I purchase.

enough for the anticipated pies, I guess. Sure there's not something more you want to tell us? Like how many lbs it takes to make a pie? Or how many cups, or something?

If you really don't know any more than this, better look online for recipes, and they'll tell you about how much you'll need.
