Question 471918
<font face="Times New Roman" size="+2">


Let *[tex \Large x] represent the number of student tickets sold.


Let *[tex \Large y] represent the number of adult tickets sold.


Let *[tex \Large T] represent the total number of tickets sold.


Let *[tex \Large D] represent the number of student tickets that exceeded the number of adult tickets.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x\ +\ y\ =\ T]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x\ =\ y\ +\ D]


Substitute from the 2nd equation into the first equation:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ (y\ +\ D)\ +\ y\ =\ T]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 2y\ =\ T\ -\ D]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ y\ =\ \frac{T\ -\ D}{2}]


And that is as far as anyone can go without the information you left out.

*[tex \LARGE e^{i\pi} + 1 = 0]
My calculator said it, I believe it, that settles it
