<PRE><B>Question 246199</B>
A theater group plans to sell 750 tickets for a play.
Quantity Equation: O + M + B = 750
-----------------
 
They are charging $12 for orchestra seats, $8 for mezzanine seats, and $6 for balcony seats, and they plan to collect $7290. 
Value Equation: 12R + 8M + 6B = 7290 dollars
----------------

There are 100 more orchestra seats than mezzanine and balcony tickets combined.
Quantity Equationg: R = (M+B)+100
--------------------------------

How many of each type of ticket were sold?
---------------------------------------------------
You have three equations in three unknowns.
Solve the system of equations in any way you know how.
