conversations.value: 400 adults and 200 children go to a Broadway show. The price of an adult ticket is twice that of a child's ticket. What is the price of an adult ticket if the total amount collected is $16,000?
  Give me a detailed solution.

conversations.value: Let X be the price of a child ticket.
  So the price of an adult ticket is X*2.
  We know from the problem that 400*X*2 + 200*X = 16,000.
  After multiplying, we have 800*X+ 200*X = 16,000.
  Combining like terms, we have 1000* X = 16,000.
  Dividing both sides by 1000, we have X = $16.
  The price of an adult ticket is $16 * 2 = $32.
