Let number of adult tickets be a , therefore number of student ticket be a+4 .
And total cost of the tickets is 58, that is
![3.50a +2.50(a+4)=58](https://tex.z-dn.net/?f=%203.50a%20%2B2.50%28a%2B4%29%3D58%20)
Distributing 2.50 on a+4
![3.50a+2.50a+10=58](https://tex.z-dn.net/?f=%203.50a%2B2.50a%2B10%3D58%20%20)
Combining like terms
![6a=48 \\ a=8](https://tex.z-dn.net/?f=%206a%3D48%0A%5C%5C%0Aa%3D8%20)
Number of adult tickets are 8 and number of students tickets are 12.
