Answer to Question #6710 in Real Analysis for Jeremy Loncar
A cafeteria offers a complete dinner that includes one serving each of appetizer, soup, entrée, and dessert for $6.99. If the menu has four appetizers, four soups, seven entrées, and two desserts, how many different meals are possible?
As menu has 4 appetizers, 4 soups, 7 entrées, and 2 desserts, we can compose one complete dinner that consists of appetizer, soup, entrée, and dessert in N = 4*4*7*2 = 224 ways. So, 224 different meals are possible.
