Answer: The occupancy rate is r = 0.783
Explanation:
You can calcuate the occupancy rate by dividing the number of rented rooms by the total number of rooms.
For example, if the number of total rooms is 115, and you rented N rooms, you will have:
r = N/115
Where N can be any whole number between 0 and 115
Now, in this case we have that the number of rented rooms is 90, so we have that:
r = 90/115 = 0.783
If you want it as an percentage, you can multiply it by 100%.
0.783*100 = 78.3%
