Answer:
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
