Question

soybean meal is 12% protein;cornmeal is 6% protein. How many pounds of each should be mixed together in order to get 240-lb mixture of protein?

Answer 1

X - 12% protein

240 -x - 6% protein

 Mixture of 0.08

 

   X ( 0.12) + ( 240 - X ) ( 0.06) = 240( 0.08)

 

    X ( 0.06) + 14.4 = 19.2

 

   X ( 0.06) = 4.8

 

    X = 80   Pound of Cornmeal

 

   240 - 80 = 160  pound of Soybean
