    Answer:

      84 adult tickets

    Step-by-step explanation:

    Let ‘a’ represent the number of adult tickets sold. Then (135-a) is the number of child tickets sold, and total revenue is …

      5.70(135 -a) +9.40(a) = 1080.30

      3.70a = 310.80 . . . . . . . . subtract 769.50 and simplify

      a = 310.80/3.70 = 84

    84 adult tickets were sold on Sunday.
