problem_description: Statement
  
  There is a train going from Station A to Station B that costs X yen (the
  currency of Japan).
  
  Also, there is a bus going from Station B to Station C that costs Y yen.
  
  Joisino got a special ticket. With this ticket, she can take the bus for half
  the fare if she travels from Station A to Station B by train and then travels
  from Station B to Station C by bus.
  
  How much does it cost to travel from Station A to Station C if she uses this
  ticket?
