Problema Solution
Soybean meal is 16% protein and corn meal is 9% protein. How many pounds of each should be mixed to get a 350 pound mixture that is 12% protein?
Answer provided by our tutors
We can write:
.16n+.09(350-n)=.12(350)
where 'n' is the amount of 16% needed and '350-n' is the amount of 12% needed. Solving, we get:
n=150
350-n=100
Therefore, we need 150 lbs of the 16% and 100 lbs of the 12%
