267 i think. I might have counted wrong

Answer 2

Answer:

39 seats are not being used in the auditorium.

Step-by-step explanation:

We have bee given the total number of seats:

In middle school auditorium are 342

Seats used  by teachers are 75

And seats used by students are $\frac{2}{3}\text{of the seats}$

And $\frac{2}{3}\cdot 342=228$seats used  by students

That means  228+75=303 seats are used

We need to calculate seats not being used which is equal to

Total seats minus  seats used =342-303 =39 seats remain unused.
