To find the number of main floor tickets the venue offers for each show, we can set up a system of equations based on the given information.
Let's denote the number of balcony tickets sold as "b" and the number of main floor tickets sold as "m".
From the problem, we know that the balcony tickets cost $30 each, and the main floor tickets cost $55 each. We also know that the total number of tickets sold for a given show is 500, and the total earnings from ticket sales is $20,000.
Using this information, we can set up the following equations:
Equation 1: b + m = 500 (since the total number of tickets sold is 500)
Equation 2: 30b + 55m = 20,000 (since the total earnings from ticket sales is $20,000)
To solve this system of equations, we can use substitution or elimination.
Let's solve using elimination:
Multiply Equation 1 by 30 to eliminate "b" and get:
30b + 30m = 15,000
Subtract Equation 2 from this new equation:
(30b + 30m) - (30b + 55m) = 15,000 - 20,000
30b + 30m - 30b - 55m = -5,000
-25m = -5,000
Divide both sides by -25:
m = -5,000 / -25
m = 200
Therefore, the venue offers 200 main floor tickets for each show.
