conversations.value: Explain how to solve this math problem: Lex is picking apples in his apple orchard when he notices some of the apples have bruises and some have worms. He wants to save the bruised apples to make applesauce, throw the wormy apples away, and keep the unbruised apples to eat raw. By his count, a fifth of the apples have worms and nine more than one fifth are bruised. He picked 85 apples. How many apples will he have left to eat raw?

conversations.value: A fifth of the apples have worms, so Lex has to throw 85 / 5 = 17 apples away.
  Nine more have bruises than worms, so Lex has 17 + 9 = 26 apples for applesauce.
  He picked 85 apples, so Lex has 85 - 26 - 17 = 42 apples left to eat raw.
