Soybean meal is 12%protein corn meal is 6% proteinhowmany pounds of each should be mixed together in order to get 240pounds mixture that is 11%protein?

Answer 1

Ok I think I haave 200pounds of soymeal and 40 pounds of corn meal

s=240-c.12s=.06c=11*240
28.8-.12c+.06c=26.4
-.06c=-.2.4
c=40
240=40+s
s=200
Correct?

Answer 2

amount of 12% corn meal -- x pounds
amount of 6% corn meal --- 240-x

solve :
.12x + .06(240-x) = .11(240)
times 100
12x + 6(240-x) = 11(240)
12x + 1440 - 6x = 2640
6x = 1200
x = 200

200 pounds of the 12% stuff and
40 pound of the 6% stuff
