Question 447845
Courtside seats ----------x $10
balcony seats ------------2x$8
end zone seats ------------y $7
capacity 12000
Receipts =$99,000

..
x+2x+y = 12000
3x+y=12000
10x+8*2x+7y=99000
26x+7y= 99000

3x+y=12000	.............1	
26x+7y=	99000	.............2	
Eliminate y								
multiply (1)by 		-7						
Multiply (2) by		1						
-21x-7y=	-84000		
26x+7y=	99000		
Add the two equations								
5x=15000		
/5							
x=	3,000
plug value of x	in (1)				
3x+y=	12000		
9000+y=12000		
y=12000	-9000
y=3000		
	
Courtside seats ----------x ----3000
balcony seats ------------2x----6000
end zone seats ------------y----3000

	
CHECK								
								
3	x	+	1	y	=	12000		
9000			3000		=	12000
