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?
They cost 2.25*100=<T>multiply(2.25, 100)=225.0 cents each.
At the bulk rate, they are 24/12=<T>divide(24, 12)=2.0 dollar each.
They cost 2*100=<T>multiply(2, 100)=200 cents each.
225-200=<T>subtract(225, 200)=25 cents are saved per bagel.
