How to calculate the average daily income of hotel rooms?

Average daily room rent = room income ÷ number of saleable rooms ÷ average daily rent = room income ÷ number of saleable rooms (excluding bad rooms) ÷ average daily rent of sold houses = room income ÷ number of sold rooms (number of rooms opened on the same day) occupancy rate = number of rooms opened on the same day ÷ total number of rooms opened ×/kloc-0.
