conversations.value: Meena bakes 5 dozen cookies for the school’s bake sale.  She sells 2 dozen cookies to her biology teacher, Mr. Stone.  Her friend Brock buys 7 cookies, and her friend Katy buys twice as many as Brock.  How many cookies does Meena have left?
  How to solve this?
conversations.from: assistant
conversations.value: Meena bakes a total of 5 x 12 = 60 cookies.
  Mr. Stone buys 2 x 12 = 24 cookies.
  Brock buys 7 cookies, so Katy buys 2 x 7 = 14 cookies.
  Meena sells a total of 24 + 7 + 14 = 45 cookies.
  She has 60 - 45 = 15 cookies left.
