anonymous · Answer

Let x = number of adult tickets.
Let y = number of child tickets.

15.25x + 4.50y = 28 725
x + y = 2800

Using the process of elimination:

15.25x + 4.50y = 28 725
4.50x + 4.50y = 12 600

= 10.75x = 16125
Therefore, x = 1500.
Therefore, 1500 adult tickets were sold.
