soybean is 12% protien, cornmeal is 6% protien. How many pounds of each should be mixed together in order to get a 240 pound mixture that is 9% protien
------------------
Since 9% is halfway between 12% and 6% (it's the average), it will take equal amounts.
So it's 120 pounds of each.
------------------
If the problem didn't ask for the average, it'd be more complicated. But always look for the quick and easy way, especially on a timed test.
