I want to make a mixture of feed that is 16% protein. I need a total of 2000 pounds, so I'm after 320# of protein.
I can mix soybean which is 48.5% and milo which is 9%. I'm not sure how to figure out the answer.

Soybean - 354.43 pounds
Milo - 1645.57 pounds


Soybean 48.5% - x pounds
Milo 9% - y pounds
Total mix - 2000 pounds
Protein 16 %- 320 pounds
x+y=2000
0.485x+0.09y=320 -->
0.485x+(2000-x)*0.09=320 -->
x=354.43 pounds & y=2000-354.43=1645.57 pounds
