<PRE><B>Question 447845</B>
The total number of seats in a basketball sports arena is 12,000. The arena is divided into three sections, court sides, end zone and balcony, and there are twice as many balcony seats as court side seats. For the conference championship game, ticket price were $10.00 for court side, $8.00 for balcony and $7.00 for end-zone. If the arena was sold out for the game and the total receipts were $99,000 how many seats were court-side???....
----
Seat Equation: c + e + b = 12000
Seat Equation:-2c+ 0 + b = 0
Value Equation:10c+7e+8b = 99,000
========================================
I used a matrix function on a TI-84 to get:
court  = 3000 seats
end zone = 3000 seats
balcony = 6000 seats
