Answer: The occupancy rate is 0.783
Explanation:
If 115 guestrooms are the total number of guestrooms, this means that if they sold 115 of their rooms, the occupancy rate will be 100%.
Then we take 115 as 100%, and now we want to see which percentage represents the 90 sold rooms.
We can do it by the relation:
Rate = (90/115) = 0.783
This means that the occupancy rate on that Saturday night is 0.783, which means that 78.3% of the total number of rooms is taken.
