Unformatted text preview: G The McDonald's Cherry Pies look very appetizing from behind the counter. A picture of a pie hangs upon the wall of the restaurant with cherries flowing from a tender, brown crust. The pie itself comes in a carton with more than 160 cherries pictured on it. Consumer Reports indicated in an article that the cherry pies do not contain the amount of cherries regulated by law. The Consumer's Union stated that FDA regulations require that a cherry pie must contain at least 25% cherries by weight. Their investigation with four New York restaurants revealed that there were an average of 5 cherries per pie, which amounted to 20% by weight. Intrigued by this, a group of seven San Diego State University business school students did their own survey. They each went to a different McDonald's in their area and bought several cherry pies and dissected them and counted the number of cherries.
