Question 436332
Let x = the number of pounds of soybeans
Then 360-x = the number of pounds of cornmeal
A 360 lb. 12% mixture contains 0.12*360 = 43.2 lb
So we can write the following equation:
0.18x + 0.09(360-x) = 43.2
Solve for x:
0.09x = 43.2 - 32.4 = 10.8 -> x = 120
So the number of lbs of soybeans = 120
And the number of lbs of cornmeal = 360-120 = 240
