A middle school took all of its 6th grade students on a field trip to see a ballet. The students filled 570 seats, which was 95% of the total number of seats in the theatre. How many total seats were in the theatre?

28 seats I think

Step-by-step explanation:

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
