**MathMate**, Monday, June 28, 2010 at 7:12pmStart with:

18-13=5 lbs of cornmeal

13-9=4 lbs of soybeanmeal.

Total = 9 lbs.

Percentage of protein = (5*0.18+4*0.09)/(5+4)

= 13%

So for 360 lbs,

weight of cornmean=(360/9)*5=200 lbs

weight of soybeanmeal = (360/9)*4=160 lbs.

By algebra:

Let x=weight of cornmeal

(360-x)=weight of soyabeanmeal

(x*0.09+(360-x))/360 = 0.13

Solve for x (=200 lbs of cornmeal)

and 160 lbs of soyabeanmeal.
