Question 974969
<font face="Times New Roman" size="+2">


Let *[tex \Large x] represent the number of students and let *[tex \Large y] represent the number of parents.


We are given that there are 326 students and parents, so:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x\ +\ y\ =\ 326]


Since student tickets are valued at *[tex \Large $5] and there are *[tex \Large x] students, the value of all of the student tickets must be *[tex \Large 5x] dollars.  Likewise, the value of all of the parent tickets are worth *[tex \Large 8y] dollars.  Furthermore, the total value of all the tickets was *[tex \Large $1792], so we can say:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 5x\ +\ 8y\ =\ 1792]


Solve the two by two linear system and report the value of *[tex \Large x], the number of students.
