conversations.value: Georgina owns a parrot and is teaching it to speak. So far, the parrot knows seventeen phrases. If she is teaching it two phrases a week and it already knew three phrases when she bought it, how many days has Georgina had it?

conversations.value: The parrot knew 3 phrases when Georgina bought it, so it has learned 17 - 3 = 14 phrases from her.
  She has been teaching it 2 phrases a week, so she has had it 14 / 2 = 7 weeks.
  There are 7 days in a week, so Georgina has had the parrot for 7 * 7 = 49 days.
