Answer:
Sold student tickets: 130, sold adult tickets: 110
Step-by-step explanation:
Let s = number of student tickets sold,
Let a = number of adult tickets sold.
[tex]s = 20+a[/tex] (It is given that there were 20 more student tickets sold than adult tickets)
[tex]s+a=240[/tex] (It is given that the total tickets sold is 240)
[tex]20+a+a = 240[/tex]
[tex]2a=220[/tex]
[tex]a = 110[/tex]
We can use substitution to find the number of student tickets:
[tex]s+a = 240[/tex]
[tex]s + 110 = 240[/tex]
[tex]s = 130[/tex]
∴110 adult tickets and 130 student tickets were sold.
I hope this helps :)
