The formula to calculate the Hotel Cost (HC) is:
\[ HC = \frac{R - P}{NR} \]
Where:
Let's say the total hotel revenue (R) is $50,000, the total hotel profit (P) is $20,000, and the number of rooms sold (NR) is 100. Using the formula:
\[ HC = \frac{50,000 - 20,000}{100} = 300 \]
So, the hotel cost (HC) is $300 per room.
