Final answer:
To find the total number of seats in the theatre, divide the number of filled seats by the percentage that represents them.
Step-by-step explanation:
To find the total number of seats in the theatre, we can set up the equation:
55% of the total number of seats = 2200
To solve for the total number of seats, we can divide both sides of the equation by 0.55:
Total number of seats = 2200 / 0.55
Simplifying the right side of the equation gives us:
Total number of seats = 4000
Therefore, the total number of seats in the theatre is 4000.
