2. **Cost Analysis**: Calculate fixed and variable costs to ensure profitability.
3. **Segmentation**: Identify target customer segments (business, leisure, luxury, budget).
4. **Dynamic Pricing**: Implement flexible pricing based on occupancy rates, seasonality, and local events.
5. **Value Proposition**: Highlight unique features and services to justify pricing.
6. **Promotions and Discounts**: Develop special offers to attract different customer segments.
7. **Feedback Loop**: Continuously gather customer feedback and adjust pricing based on market changes and performance metrics.

Right Answer:
The decline in profits despite growing sales could be due to rising costs, such as increased labor, raw materials, or operational inefficiencies. Additionally, it may be caused by pricing pressures, higher competition, or increased overhead expenses. Analyzing the cost structure and operational processes is essential to identify the specific reasons.

Right Answer:
To determine if the ERP system was a financially sound investment, we need to analyze the return on investment (ROI). We should compare the cumulative benefits gained from the ERP system over the past 3 years against the $100M spent. If the benefits exceed $100M, it was a sound investment; if not, it was not financially sound.

Right Answer:
The process of refrigeration involves removing heat from a designated area to lower its temperature. This is typically achieved using a refrigerant that absorbs heat as it evaporates in the evaporator coil, then compresses to increase pressure and temperature in the compressor, and finally releases the absorbed heat in the condenser coil as it condenses back into a liquid. This cycle repeats to maintain a cool environment.

Right Answer:
The formula to calculate machine capability (Cp) is:

Cp = (USL - LSL) / (6 * σ)

And for process capability (Cpk):

Cpk = min[(USL - μ) / (3 * σ), (μ - LSL) / (3 * σ)]

Where:
- USL = Upper Specification Limit
- LSL = Lower Specification Limit
- μ = Mean of the process
- σ = Standard deviation of the process
