Answer:
24
Explanation:
Given that the cost for one ticket for a student =$6
The cost for one ticket for an adult =$10
The theater sold 100 tickets and raises $904.
Let x students attend the performance.
So, the number of adults who attend the performance= 100-x
Total cost for the tickets = 6x+10(100-x)

Hence, 24 students attend the performance.
