275 students and 113 non-students attended the event.
Step-by-step explanation:
Let,
Student ticket = x
Non-student ticket = y
Price of one student ticket = $3.50
Price of one non-student ticket = $5.50
According to given statement;
x+y=388 Eqn 1
3.50x+5.50y=1584.00 Eqn 1
Multiplying Eqn 1 by 3.50
![3.50(x+y=388)\\3.50x+3.50y=1358\ \ \ Eqn 3](https://tex.z-dn.net/?f=3.50%28x%2By%3D388%29%5C%5C3.50x%2B3.50y%3D1358%5C%20%5C%20%5C%20Eqn%203)
Subtracting Eqn 3 from Eqn 2
![(3.50x+5.50y)-(3.50x+3.50y)=1584.00-1358\\3.50x+5.50y-3.50x-3.50y=226\\2y=226\\Dividing\ both\ sides\ by\ 2\\\frac{2y}{2}=\frac{226}{2}\\y=113](https://tex.z-dn.net/?f=%283.50x%2B5.50y%29-%283.50x%2B3.50y%29%3D1584.00-1358%5C%5C3.50x%2B5.50y-3.50x-3.50y%3D226%5C%5C2y%3D226%5C%5CDividing%5C%20both%5C%20sides%5C%20by%5C%202%5C%5C%5Cfrac%7B2y%7D%7B2%7D%3D%5Cfrac%7B226%7D%7B2%7D%5C%5Cy%3D113)
Putting y=113 in Eqn 1
![x+113=388\\x=388-113\\x=275](https://tex.z-dn.net/?f=x%2B113%3D388%5C%5Cx%3D388-113%5C%5Cx%3D275)
