Final answer:
By using the fundamental counting principle, we can calculate that the total number of possible lunch meals is 105, given the choices of 3 appetizers, 5 veggie salads, and 7 main courses.
Step-by-step explanation:
The student asked how many lunch meals consisting of 1 appetizer, 1 veggie salad, and 1 main course are possible with a given menu from a fast food chain. To calculate the total number of possible meals, we can use the fundamental counting principle which says that if there are n ways to perform a task and m ways to perform another task, then there are n × m ways to perform both tasks in sequence.
In this case, the fast food chain offers 3 appetizers, 5 veggie salads, and 7 main courses. We can multiply the number of choices for each course to determine the total number of possible lunch meals:
- 3 choices for appetizers
- 5 choices for veggie salads
- 7 choices for main courses
Therefore, the total number of possible lunch meals is:
3 appetizers × 5 veggie salads × 7 main courses = 105 lunch meals
The complete question is:
A new fastfood chain offers a menu consisting 3 appetizers, 3 soups, 5 veggie salads, 7 main courses, and 4 desserts. How many lunch meals consisting of 1 appetizer, 1 veggie salad, and 1 main course are possible?
