conversations.value: A show debut and 200 people buy tickets.  For the second showing three times as many people show up.  If each ticket cost $25 how much did the show make?
conversations.from: assistant
conversations.value: The second show sold 200*3=600 tickets
  So there were a total of 200+600=800 tickets sold
  That means they made 800*25=$20,000
