A middle school took all of its 6th grade students on a field trip to see a play. The students filled 341 seats, which was 55% of the total number of seats in the theater. How many total seats were in the theater?

To find out how many total seats were in the theater, we first need to calculate what 100% of the total number of seats is based on the 55% filled by the 6th grade students.

Let x be the total number of seats in the theater.

55% of x = 341
0.55x = 341
x = 341 / 0.55
x = 620

Therefore, the theater has a total of 620 seats.
