soybean meal is 18% protein; cornmeal is 9% protein. How many pounds of each should be mixed together in order to get 360-lb mixture tha is 14% protein?

how many lbs of the cornemeal should be in the mixture and how many pounds of the soybean should be in the mixture?

same question as the previous one, except you changed the final percentage from 13% to 14%

Whichever the correct one, just make the necessary changes.
