9. October 13, 2005 8 Building a FIS from scratch  The Basic Tipping Problem. Given a number between 0 and 10 that represents the quality of service at a restaurant (where 10 is excellent), and another number between 0 and 10 that represents the quality of the food at that restaurant (again, 10 is excellent), what should the tip be?

10. October 13, 2005 9 Example: Dinner for two Golden rules for tipping: 1.IF the service is poor OR the food is rancid, THEN tip is cheap (5%). 2. IF the service is good, THEN tip is average (15%). 3. IF the service is excellent OR the food is delicious, THEN tip is generous (25%).
