Final answer:
When more guests arrive than expected, divide the cake into smaller pieces for sharing, be flexible, and maintain a welcoming atmosphere.
Step-by-step explanation:
If it's your birthday and you baked a cake for 8 people, but 25 people show up, you have a scenario that involves problem-solving and social skills, rather than a straightforward answer from a single academic subject. This is a real-life situation that could happen to anyone, and the skills you would use to solve it are related to social etiquette and perhaps basic mathematics if you choose to divide the cake into smaller portions.
You could approach the situation by evenly dividing the cake into smaller pieces so that each person gets a portion. Emphasize the importance of sharing during unexpected situations. If the cake is not enough, you could complement it with other available snacks or propose an alternative like going out to get more dessert, reinforcing the concept of flexibility and adaptability. In any case, you'd want to maintain a good atmosphere and ensure your guests feel welcome.
