Question 889589
Part I	8.00%		per annum	-------------	Amount invested =x	
Part II	7.50%		per annum	------------	Amount invested = y	
	100000					
Interest-----	7700.00					
						
Part I	8.00%		per annum	---x		
Part II	7.50%		per annum	---y		
Total investment						
x	+	1	y=	100000	-------------1	
Interest on both investments						
8.00%	x	+	7.50%	y=	7700	
Multiply by		100				
8	x	+	7.5	y=	770000.00	--------2
Multiply (1) by			-8			
we get						
-8	x	-8	y=	-800000.00		
Add this to (2)						
0	x	-0.5	y=	-30000		
divide by		-0.5				
			y	=	60000	
Part I	8.00%	$	40000			
Part II	7.50%	$	60000			
						
CHECK						
40000	---------	8.00%	-------	3200.00		
60000	-------------	7.50%	-------	4500.00		
Total			--------------------	7700.00
