Using proportions, it is found that there are 200 rooms in hotel X.
A proportion is a fraction of a total amount.
The X Hotel has an occupancy rate of 97% during busy season(30% of the year) and 62% during the rest of the year(70%), hence the mean occupancy rate is of:
R = 0.3 x 97% + 0.62 x 70% = 72.5%.
The total profit for the Pinkerton Hotel was $4,468,000, hence considering that it makes $80 per room per night, in a 365-day year:
80N x 0.725 x 365 = 4,468,000
N = 4,468,000/(80 x 0.725 x 365)
N = 211.
Which is closest to 200, hence, there are 200 rooms in hotel X.
