Explanation:
Given that Adult tickets (x) cost $20, and student tickets (y) cost $15
Since the total amount available to spend for the group is $500, the sum of the amount for adult tickets and the amount for student tickets they can buy would not exceed $500 (It can be below however)
Amount for adult tickets = 20x
Amount for students tickets = 15y
We now have the inequality:
[tex]20x+15y\le500[/tex]
