You can put this solution on YOUR website! Part I	6.00%		per annum Part II	8.00%		per annum
 
 x+y=32000	------------------------1
 6.00%x+8.00%y=$2,120.00
 Multiply by 		100
 6x+8y=$212,000.00		--------2
 
 Multiply (1) by	-6
 we get
 -6x-6y=	-192000
 Add this to (2)
 2y=$20,000.00
 
 divide by 2
 investment at 	8.00% $10,000
 Balance	$22,000.00 investment at 6.00%
