How many pounds of each should be mixed together in order to get a 240-lb mixture that is 80% protein?Answer by josmiceli(9690)   (Show Source): You can put this solution on YOUR website!*** note: there is no way you can get 80% protein from the mixture. I changed it to 8%, which I think is what you meant *** Let = pounds of soybean meal needed Let = pounds of cornmeal needed = pounds of protein in soybean meal = pounds of protein in cornmeal ---------------- (1) (2) -------------------------- (2) (2) (2) Subtract (1) from (2) (2) (1) and, since (1) (1) (1) 80 pounds of soybean meal is needed 160 pounds of cornmeal is needed check: (2) (2) (2) (2) OK
