If there were 67 more student tickets than adult tickets, and the total number of tickets sold was 567, we can set up an equation to solve for the number of adult tickets. Let's call the number of adult tickets "x".
So, the number of student tickets would be "x + 67".
According to the given information, the total number of tickets sold is 567.
Therefore, we can write the equation as:
x + (x + 67) = 567
Simplifying the equation, we get:
2x + 67 = 567
Subtracting 67 from both sides of the equation, we have:
2x = 500
Dividing both sides by 2, we find:
x = 250
So, 250 adult tickets were sold.
