Question 791569
	percent	----------------			quantity								
Solution I	10.00%	----------------			x	gallons							
solution II	40.00%	------	60	-	x	gallons							
Mixture	20.00%	----------------	60										
Total	60		gallons										
10.00%	x	+	40.00%	(	60	-	x	)	=	20.00%	*	60	
10	x	+	40	(	60	-	x	)	=	1200			
10	x	+	2400	-	40	x	=			1200			
10	x	-	40	x			=	1200	-	-2400			
-30	x			=	-1200								
/	-30												
	x			=	40		gallons			10.00%		Solution I	
					20		gallons			40.00%		solution II
