<PRE><B>Question 777876</B>
x= 	cost of	Hamburgers						
y=	cost of	fries						
Family I								
4	x	+	3	y	=	10.23	.............1	
Family II								
1	x	+	5	y	=	8.04	.............2	
Eliminate	y							
multiply (1)by		-5						
Multiply (2) by		3						
-20	x		-15	y	=	-51.15		
3	x	+	15	y	=	24.12		
Add the two equations								
-17	x				=	-27.03		
/	-17							
x	=	2						
plug value of			x	in (1)				
4	x	+	3	y	=	10.23		
6		+	3	y	=	10.23		
			3	y	=	10.23		-6
			3	y	=	3.87		
				y	=	1.29		
x=	1.59		cost of	Hamburgers				
y=	1.29		cost of	fries
