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
In point for (2,7) and in Equation form x=2 y=7
