Answer:

  • 60 adult tickets
  • 140 children's tickets

Step-by-step explanation:

Let "a" represent the number of adult tickets sold. Then the total revenue is ...

  5a +3(200-a) = 720

  2a +600 = 720 . . . . . . simplify

  2a = 120 . . . . . . . . . . . . subtract 600

  a = 60 . . . . . . . . number of adult tickets sold

  200-a = 140 . . . number of tickets for children sold
