Answer:

80

Step-by-step explanation:

Let the number of adult tickets sold be a and the number of student tickets sold be s.

  • "The drama class sold 20 more adult tickets han student tickets to the fall play." means that a-20=s.
  • "the class collected $880 from ticket sales" means that 8a+4s=880, which is the same as 2a+s=220.

Substituting the first equation into the second,

[tex]2a+a-20=220 \\ \\ 3a-20=220 \\ \\ 3a=240 \\ \\ a=80[/tex]
