Question 173893
Let x = pounds of soybean meal
then
240-x = pounds of cornmeal
.
"amt of protein from soybean" + "amt of protein from cornmeal" = "desired amt of protein"
.12x + .06(240-x) = .08(240)
.12x + 14.4 - .06x = 19.2
.06x = 4.8
x = 80 pounds (soybean meal)
.
cornmeal:
240-x = 240-80 = 160 pounds
