Well first, you have to see how many ounces are in 1 pound and there are 16 ounces in 1 pound.
So now, I am going to multiply 16×92 1/2 ( or 92.5 )
SO: 92.5
× 16
--------------
1480 ounces
8 pounds. Because you'll need 4 pounds to make 10 apple pies, 6 pounds to make 15 apple pies, and 8 pounds to make 20 apple pies.
8 x 5 = 40
40 x 18 = 720
Hope this helps!
There it is i found it :)
