Question 565911
Bonds	11.00%		per annum	----x					
Savings	6.00%		per annum	----y					
The sum of the investments is 						$40,000.00			
The sum of individual interests = 				$4,080.00					
x		+	y	40000	------------------------1				
11.00%	x	+	6.00%	y	=	$4,080.00			
Multiply by 		100							
11	x	+	6	y	=	$408,000.00		--------2	
									
Multiply (1) by			-11						
we get									
									
-11	x	-11	y	=		-440000.00			
									
Add this to (2)									
									
0	x	-5	y	=		-$32,000.00			
									
divide by		-5							
									
y	=		$6,400.00		investment at 	6.00%
Balance			$33,600.00 		investment at 	11.00%
CHECK									
$33,600.00	@	11.00%	$3,696.00						
$6,400.00	@	6.00%	$384.00
