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?
Let's think step by step below.
25
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.

The answer: 25
