Answer:
The answer would be the first one, X is greater than, or equal to, 100.
Step-by-step explanation:
The question says that no fewer than 100 people can attend. However, it doesn't say that EXACTLY 100 people can attend the dance. With that in mind, you can use the Greater than, or equal to symbol. The only situation where x > 101 would work is if the question said 'More than 100 people must attend the school dance.'
