Soybean meal is 12% protein; cornmeal is 6% protein. howmany pounds of each should be mixed together to get a 240 pound mixture that is 8% protein?
Sum of protein constituents=total protein
S + P=240
Those two equations will solve it.
I don't understand the equations I am having a lot of trouble.
S+P=240, then S=240-P
.12(240-P) + .06P=240*.08
solve for P
