Bardi Trucking Co., located in Cleveland, Ohio, makes deliveries in the Great Lakes region, the Southeast, and the Northeast. Jim Bardi, the president, is studying the relationship between the distance a shipment must travel and the length of time, in days, it takes the shipment to arrive at its destination. To investigate, Mr. Bardi selected a random sample of 20 shipments made last month. Shipping distance is the independent variable and shipping time is the dependent variable. The results are as follows:
| Shipment | Distance (miles) | Shipping Time (days) | Shipment | Distance (miles) | Shipping Time (days) | |||
| 1 | 782 | 14 | 11 | 609 | 10 | |||

5. When consumer demand for hotel rooms increases, the average selling prices for those rooms typically increase as well. In the foodservice business that has not historically been the case. Fluctuations in consumer demand (e.g., volume differences between high demand Saturday nights and lowervolume Sunday nights) in restaurants do not typically result in menu price changes. Given that both hotels and restaurants are part of the hospitality industry, how do you account for these fundamental differences in approach toward strategic pricing? As a customer, which approach do you believe sends you the better value message? Explain your position.

The company has, therefore, decided to utilise their ability to raise funds and their cash generation ability to organically expand into the hotel industry. Tesco feels that the market is open to a new participant and that companies such as Intercontinental Hotels Group plc are not ready for a vibrant new competitor. Tesco could expand by undertaking ‘organic’ growth orcould undertake the indicated growth by acquisition. You are required to provide a critical analysis of the relative benefits of the two types of growth (i.e. ‘organic’ and acquisition) from Tesco’s point of view, with regard to the proposed expansion.
