conversations.value: Emily bought 9 packs of candy necklaces * 8 candy necklaces in a pack = 72 candy necklaces.
  Her classmates took 72 candy necklaces – 40 candy necklaces left = 32 candy necklaces
  Since each pack contained 8 necklaces, this means 32 / 8 = 4 packs of candy necklaces were opened.
