Question 457414
Student tickets	x							
Non student tickets	y							
								
x+y=4000.............1	
3x+6y=	13500	.............2	
								
multiply (1)by -6						
Multiply (2) by	1						
-6x-6y=-24000		
3x+6y=13500		
Add the two equations								
-3x=-10500		
/-3							
x=3500						
plug value of 			x	in (1)				
x+y=4000		
3500+y=	4000		
y=4000-3500
y=500		
				y	=	500.00
