Part I	4.00%		per annum	---x			
Part II	7.00%		per annum	---y			
Total investment							
x	+	1	y=	67000	-------------1		
Interest on both investments

4	x	+	7	y=	373000.00	--------2	
Multiply (1) by			-4				
we get							
-4	x	-4	y=	-268000.00			
Add this to (2)							
0	x	3	y=	105000			
divide by		3					
			y	=	35000		
Part I	4.00%	$	32000
