The inequality of the most people that can be seated in the auditorium
WINSTONCH [101]
Let x be the number of people that can be seated.

The value of x is some number 0 or greater, such that this number is a whole number (we can't have half a person). This means that x \ge 0 which is the same as saying 0 \le x

The instructions state that we can seat up to 1200 people. This is the max capacity. We can't go over this amount. So we will also have x \le 1200 indicating that x can be less than 1200 or equal to 1200.

So putting the two inequalities together, we get 0 \le x \le 1200

Note: if you haven't learned about compound inequalities yet, then the teacher may only want x \le 1200 as the answer.
