The number of student tickets sold was 105

Step-by-step explanation:

Let

x ----> the number of student tickets sold

y ----> the number of adult tickets sold

we know that

If total of 230 tickets are sold for $825

then

[tex]x+y=230[/tex] ----> equation A

[tex]2.50x+4.50y=825[/tex] ----> equation B

Solve the system by graphing

Remember that the solution of the system is the intersection point both graphs

using a graphing tool

The solution is the point (105,125)

see the attached figure

therefore

The number of student tickets sold was 105
