Final answer:
The number of adult tickets sold is 275.
Step-by-step explanation:
Let's denote the number of adult tickets sold as x.
Since there were 72 more student tickets sold than adult tickets, the number of student tickets sold would be x + 72.
According to the question, the total number of tickets sold is 622.
So, we can write the equation as:
- x + (x + 72) = 622
Simplifying the equation, we get:
- 2x + 72 = 622
- 2x = 550
- x = 275
Therefore, the number of adult tickets sold is 275.
