Question: (Supermarket) Suppose you have been hired as a consultant for a supermarket chain to advise on a plan to prepare ahead of time and cook complete "package" meals to be sold as convenience items for customers. A complete package meal will include one choice from each module, i.e., one meat, one potato, one salad, and one bread item. The food menu will vary from day to day, but a typical menu looks like:

Module 1 (4 Meats): Filet mignon / Fried chicken / Pork ribs / Leg of lamb

Module 2 (3 Potatoes): Rosemary potatoes / Pan-roasted potatoes / Mashed potatoes

Module 3 (3 Salads): Garden peas / Garden salad / Fruit salad

Module 4 (3 Breads): Roll and butter / French bread and butter / Biscuit and honey

(Supermarket) How many different complete package meals can be created?
