Part I	5.00%		per annum						
Part II	4.00%		per annum						
									
x+y=10000	------------------------1				
5.00%x+	4.00%y	=$470.00			
Multiply by 	100							
5x+4y=$47,000.00		--------2	
									
Multiply (1) by	-5						
we get									
									
-5x-5y	=-50000.00			
									
Add this to (2)									
									
	-y=-$3,000.00			
y=$3,000.00 investment at 	4.00%
