conversations.value: I'm completely lost with this math problem: The bagels cost $2.25 each, or a dozen for $24. How much is saved, per bagel, in cents, by buying a dozen at a time?
  Can you give me a hand?

conversations.value: They cost 2.25*100=225 cents each.
  At the bulk rate, they are 24/12=2 dollar each.
  They cost 2*100=200 cents each.
  225-200=25 cents are saved per bagel.
