Part I	-5.00%		per annum	-------------	Amount invested =x		
Part II	7.00%		per annum	------------	Amount invested = y		
	13500						
Interest-----	171.00						
							
Part I	-5.00%		per annum	---x			
Part II	7.00%		per annum	---y			
Total investment							
x	+	1	y=	13500	-------------1		
Interest on both investments							
-5.00%	x	+	7.00%	y=	171		
Multiply by		100					
-5	x	+	7	y=	17100.00	--------2	
Multiply (1) by			5				
we get							
5	x	5	y=	67500.00			
Add this to (2)							
0	x	12	y=	84600			
divide by		12					
			y	=	7050		
Part I	-5.00%	$	6450				
Part II	7.00%	$	7050
