How to calculate the number of extended rooms?

The number of extended rooms can be calculated through the following steps:

1. Count the number of all extended rooms in the hotel, including those that have been extended and those that are about to be extended.

2. Based on the hotel's customer occupancy status, statistics and calculations are made on the rooms that have been extended.

3. Estimate the number of guest rooms that will be renewed, taking into account customer needs and hotel management.

4. Calculate the average number of extended rooms, that is, divide the sum of the number of extended rooms and the number of rooms to be extended by the total number of rooms in the hotel.
