	percent	----------------			quantity							
Protein I	75.00%	----------------			x	pounds						
Protein II	25.00%	------	1100	-	x	pounds						
Mixture	50.00%	----------------	1100									
Total	1100		pounds									
75.00%	x	+	25.00%	(	1100	-	x	)	=	50.00%	*	1100
75	x	+	25	(	1100	-	x	)	=	55000		
75	x	+	27500	-	25	x	=			55000		
75	x	-	25	x			=	55000	-	-27500		
50	x			=	27500							
/	50											
	x			=	550		pounds			75.00%		Protein I
					550		pounds			25.00%		Protein II
