If 480 tickets cost $2580, 1 student ticket is $4, 1 adult is $6. Lets try dividing. 2580/6 and 2580/4. 2580/6=$430 and 2580/4=$645 again. 4 dollars per student and 6 dollars per adult. for the students, I would say approx. of 215 student tickets sold. And for the adults 215 dollars as well. to know this, I looked up multiples of them both. and 215 was the common one. So 215 adult tickets were sold and 215 student tickets were sold
