conversations.value: A mum ordered 80 cupcakes for her daughter's birthday. Half of them are gluten-free. There are 24 vegan cupcakes and half of them are also gluten-free.  How many are non-vegan cupcakes that also contain gluten?

conversations.value: The gluten-free cupcakes are 80 / 2 = 40.
  The vegan cupcakes with gluten are 24 / 2 = 12.
  The non-vegan cupcakes with gluten are 40 - 12 = 28.
