Harry's Such a Card
Responding to a comic book ad with the promise "Get Rich Quick," Harry decides to sell Cheesy Greeting Cards. Unfortunately, he has fewer relatives and friends to buy the cards than he thought, and his attempts to sell them on the street are not successful. When he calculates the amount sold, he is pleasantly surprised that the total is more than $250. Ballpark estimation confirms that this sum is unreasonable, and shows that it's possible to make a mistake even when using an adding machine.
Math message: To be confident about your solution to a problem, make sure the answer is reasonable - that it is "in the ballpark."
