Answer:

  90 adults; 160 students

Step-by-step explanation:

Let "a" represent the number of adults who went. The number of students can be represented by (250-a). Then the total cost of tickets is ...

  4.50a +2.50(250-a) = 805

  2a + 625 = 805 . . . . . . simplify

  2a = 180 . . . . . . . . . . . . subtract 625

  a = 90 . . . . . . . . . . . . . . divide by 2

  # of students = 250 -90 = 160

160 students and 90 adults went to the movies.
