Hey..please help me with this word problem: The auditorium at Centennial High Schoool has one thousand seats. numbered from 1 to 1000, One day each seat was filled and the 1000 people followed these directions:
First, each person stood up. Next, every second person, including the person in seat two sat down. Then every third person including the person in seat 3, changed to the opposite. That is, if the person was standing, he or she sat down. If the person was sitting, he or she stood up.
Following this, every fourth person, including the person in seat 4, changed to the opposite. Then, every fifth person, including the person in seat 5, changed to the opposite, and so on. Finally, the one thousandth person changed to the opposite. After this last change, was the one thousandth person sitting or was that person standing?
Questions: 1. Was the person in seat 1 sitting or was that person standing? 2. For which of the seats 120 were people sitting? Standing? 3. Was the person in seat 1000 sitting or was that person standing? 4. For which of seats 11000 were people standing?
