Imagine that you go in to work on Monday, and your boss
tells you that you're getting a raise. Your pay will be doubled. Great!
On Tuesday, you get a letter from your landlord. Beginning
next month, your rent will be doubled.
On Wednesday, you go shopping and discover that a loaf of bread
costs twice what it did last week.
On Thursday, you go to buy gas. Turns out, the price at the
Shell station is double what it was before.
