Answer:
- 455 adult tickets
- 884 student tickets
Step-by-step explanation:
Let "a" represent the number of adult tickets sold. Then 1339-a is the number of student tickets sold. The revenue collected was ...

(1339-a) = 884 . . . . student tickets sold
455 adult tickets and 884 student tickets were sold.
