Question 866206
Part I	3.50%		per annum	-------------	Amount invested =x	
Part II	5.00%		per annum	------------	Amount invested = y	
	20000					
Interest-----	790.00					
						
Part I	3.50%		per annum	---x		
Part II	5.00%		per annum	---y		
Total investment						
x	+	1	y=	20000	-------------1	
Interest on both investments						
3.50%	x	+	5.00%	y=	790	
Multiply by		100				
3.5	x	+	5	y=	79000.00	--------2
Multiply (1) by			-3.5			
we get						
-3.5	x	-3.5	y=	-70000.00		
Add this to (2)						
0	x	1.5	y=	9000		
divide by		1.5				
			y	=	6000	
Part I	3.50%	$	14000			
Part II	5.00%	$	6000			
						
CHECK						
14000	---------	3.50%	-------	490.00		
6000	-------------	5.00%	-------	300.00		
Total			--------------------	790.00
