A hog producer is feeding soybean meal and corn to his pigs. He needs to know how many pounds he needs to feed of each in order to meet his pig's crude protein requirements. Feed one, soybean meal has a 45% crude protein and feed 2, corn has a crude protein percent of 15% the desired crude protein percent for the pigs is 25%. Calculate how many pounds of each feed the hog producer will need to feed his pigs and this example 1 ton (2,000 ibs.) of feed is needed. The parts of each feed can be expressed as a percent simply by dividing the individual parts by the total parts and multiplying by 100.
