Answer:

225

Step-by-step explanation:

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

  • "A total of 384 tickets were sold for the school play" means a+s=384.
  • "66 fewer student tickets sold than adult tickets" means s=a-66.

Substituting the second equation in the first yields

[tex]a+a-66=384 \\ \\ 2a-66=384 \\ \\ 2a=450 \\ \\ a=225[/tex]
