Question 565904
Investment I	8.00%		per annum	----x					
Investment II	6.00%		per annum	----y					
The sum of the investments is 		$8,100.00			
The sum of individual interests = 	$564.00					
x		+	y	8100	------------------------1				
8.00%	x	+	6.00%	y	=	$564.00			
Multiply by 		100							
8	x	+	6	y	=	$56,400.00--------2	
									
Multiply (1) by			-8						
we get									
									
-8x-8y=	-64800.00			
									
Add this to (2)									
									
0x-2y=-$8,400.00			
									
divide by-2							
									
y	=		$4,200.00		investment at 	6.00%
Balance			$3,900.00		investment at 	8.00%
CHECK									
$3,900.00			$312.00						
$4,200.00			$252.00
