Detailed explanation-1: -5*3*4 = 60, so 60 different main meals could be ordered.

Detailed explanation-2: -This can also be achieved by multiplication: 2 appetizers * 4 main dishes * 3 desserts = 2*4*3 = 24 combinations. Now adding salad dressings and ice cream choices. If there are four choices of salad dressing, then we can say there are 4 different salads and therefore 5 total different appetizers.

Detailed explanation-3: -Full Course Meals This will add to the course length, so a four-course dinner will include an appetizer, main dish, and dessert but also a fourth course-hors-d’oeuvres-served before the appetizer.

Detailed explanation-4: -This then implies that there are 200 different meals available (when a meal consists of an appetizer, entrée and dessert).

Detailed explanation-5: -The three-course meal includes an appetizer, entrée, and dessert. The first course of the three-course meal is a salad.
