Answer by John10(297) About Me  (Show Source):
You can put this solution on YOUR website!
Let s be the amount of Soybean and c is the amount of cornmeal
The total is 320 lbs: s + c = 320
The mixture is 0.16s + 0.08c = 320(0.15)= 48
Solve this system:
s + c = 320
0.16s + 0.08c = 48
Hint: s = 280 lbs and c = 40 lbs
There you go!
