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
[tex]3.50(x+y=388)\\3.50x+3.50y=1358\ \ \ Eqn 3[/tex]
Subtracting Eqn 3 from Eqn 2
[tex](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[/tex]
Putting y=113 in Eqn 1
[tex]x+113=388\\x=388-113\\x=275[/tex]
275 students and 113 non-students attended the event.
