You can  put this solution on YOUR website! Fund A	3.00%		per annum	-------------		x		 
Fund B	7.00%		per annum	------------	y=	2x						 
Interest-----	$1,700.00						 
								 
3.00%	x	+	7.00%	*	2	x	=	$1,700.00 
0.03	x	+	0.07	*	2	x	=	$1,700.00 
0.03	x	+	0.14	x	=	$1,700.00		 
0.17	x	=	$1,700.00					 
/	0.17							 
x=	$10,000.00	---	Fund A					 
2	x	=	$20,000.00		Fund B			 
								 
	CHECK							 
	$300.00	+	$1,400.00	=	$1,700.00
