Question 685475
Part I	8.00%		per annum	-------------	Amount invested =x	
Part II	4.00%		per annum	------------	Amount invested = y	
	2000					
Interest-----	132					
						
Part I	8.00%		per annum	---x		
Part II	4.00%		per annum	---y		
Total investment						
x	+	1	y=	2000	-------------1	
Interest on both investments						
8.00%	x	+	4.00%	y=	132	
Multiply by		100				
8	x	+	4	y=	13200.00	--------2
Multiply (1) by			-8			
we get						
-8	x	-8	y=	-16000.00		
Add this to (2)						
0	x	-4	y=	-2800		
divide by		-4				
			y	=	700	
Part I	8.00%	$	1300			
Part II	4.00%	$	700			
						
CHECK						
1300	---------	8.00%	-------	104.00		
700	-------------	4.00%	-------	28.00		
Total			--------------------	132.00
