Question 771153
We assume it is diluted with water which has 0% strength


	percent	----------------			quantity								
solution I	70.00%	----------------			x	liters							
Water	0.00%	------	3	-	x	liters							
Mixture	30.00%	----------------	3										
	3												
70.00%	x	+	0.00%	(	3	-	x	)	=	30.00%	*	3	
70	x	+	0	(	3	-	x	)	=	90			
70	x	+	0	-	0	x	=			90			
70	x	-	0	x			=	90	-	0			
70	x			=	90								
/	70												
	x			=	1.29		liters			70.00%		solution I	
					1.71		liters

	30.00%		Water	
										
we need 1.29 liters of solution
1 liter = 33.81 fl oz.	
1.29 liter = 	43.62 fl. oz

1 bottle = 8 fl.oz
43.62 fl. Oz = 5.45 bottle = 6 bottles
