Question 583459
part I   	4.00%		per annum	---x					
part II	2.00%		per annum	---y					
									
x+y=3200	------------------------1				
4.00%	x	+	2.00%	y=	98				
Multiply by		100							
4x+2y=	9800.00		--------2	
									
Multiply (1) by			-4						
we get									
									
-4x-4y=	-12800.00			
									
Add this to (2)									
									
0x-2y=	-3000			
									
divide by		-2							
									
y	=		1500		investment at	2.00%
Balance			1700		investment at	4.00%
CHECK									
1500	---------	2.00%	-------	30.00					
1700	-------	4.00%	-------	68.00
