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 lb mixture that is 12% protein
Answer provided by our tutors
let 'x' represent the amount of 16% soybean meal used, then '350-x' represents the amount of 9% corn meal used
0.12(350) = 0.16x + 0.09(350-x)
solving for 'x' we have x=150
350-150 = 200
150 pounds of the 16% soybean meal was combined with 200 pounds of the 9% corn meal
