Question 605163
Part I  	9.00%		per annum	---x		
Part II   	4.00%		per annum	---y		
Sum of investments						
x	+	1	y=	16000	-------------1	
Interest earned on both investments						
9.00%	x	+	4.00%	y=	900	
Multiply by		100				
9	x	+	4	y=	90000.00	--------2
Multiply (1) by			-9			
we get						
-9	x	-9	y=	-144000.00		
Add this to (2)						
0	x	-5	y=	-54000		
divide by		-5				
			y	=	10800	
Part I  	4.00%	$	10800			
Part II   	9.00%	$	5200			
						
CHECK						
10800	---------	4.00%	-------	432.00
