Question

soybean meail is 18% protein; cornmeal is 9% protein. How many pounds of each should be mixed together in order to get 360-lb mixture that is 13% protein?

Answer 1

Sure?

Answer 2

You need to mix together 160lbs of soybean meal and 200 lbs of cornmeal.

At 13% protein, 360 lb of the mixture will contain 46.8 lb of protein.

160lbs of soybean meal at 18% protein will give you 28.8 lb of protein; 200lbs of cornmeal at 9% protein will give you 18 lb of protein.

160 lb soybean + 200 lb cornmeal = 360 lbs of mixture;

28.8 lb of soybean protein + 18 lb of cornmeal protein = 46.8 lb (13%) of protein.
