Question 576724
I think the inheritance must be $36,500 and not 365,000

Teri	9.00%		per annum	---x					
Tammy	8.50%		per annum	---y					
									
x+y=	36500	------------------------1				
9.00%x+8.50%y=	3200				
Multiply by		100							
9x+8.5y=320000.00		--------2	
									
Multiply (1) by			-9						
we get									
									
-9	x	-9	y=			-328500.00			
									
Add this to (2)									
									
0	x	-0.5	y=	=		-8500			
									
divide by		-0.5							
									
y=17000		investment at	8.50%
Balance	19500	investment at	9.00%
CHECK									
17000	---------	8.50%	-------	1445.00					
19500	-------	9.00%	-------	1755.00					
Total			--------------	3200.00
