Johnny, despite his mother's objections, spent his whole allowance of \$2.16 (\$2.00, with 16 cents left from last week) on bubble gum. If the pieces of gum had been a penny cheaper, he would have received three more pieces than he did.

You've bought your weekly egg supply at the local farm store. The first morning you have company for breakfast and use half the eggs plus one-half an egg. The next morning you use one-half of what's left plus one-half an egg. The third morning you use one-half of what's left plus one-half an egg, and on the fourth morning, you're down to one solitary egg, so you make French toast. In all this cooking, you've never had one-half an egg to carry over to the next day.
