Question 430149
Part I	8.00%		per annum						
Part II	6.00%		per annum						
									
x+y=15000------------------------1				
8.00%x+	6.00%y=$1,000.00			
Multiply by 	100							
8x+6y=$100,000.00--------2	
									
Multiply (1) by	-8						
we get									
									
-8x-8y=-120000.00			
									
Add this to (2)									
									
-2y=-$20,000.00			
									
divide by	-2							
									
y=$10,000.00	investment at 	6.00%
Balance	$5,000.00 investment at 8.00%
