Question 546488
percent		----------------			quantity							
Acid solution I	30	----------------			x	L						
Acid solution II	42	------	15	-	x	L						
Mixture	32.00%	----------------	15									
												
30	x	+	42	(	15	-	x	)	=	32	*	15
												
30	x	+	630	-	42	x	=			480		
30	x	-	42	x			=	480	-	630		
-12	x			=	-150							
/	-12											
	x=	12.5L	30.00%	Acid solution I
	2.5L	42.00%		Acid solution II
