We believe that the Department store is represented by column K. The first aspect that caught our attention was the fact that there was a very large amount of inventory, which makes sense because a department store will need to have a continuous flow of inventory in order to make sure the most current goods are being represented on the shelf, while the older items get cycled out. Also, column K had a relatively low inventory turnover due to the fact that it will only completely sell its inventory a few times a year. This will be sold to either the customers of the store or to different resellers, who will buy the goods at a discounted price and sell them for a cheaper price to customers. Another aspect of column K is the fact that the collection period is 16 days. This is due to the fact that they issue their own charge card, which is most likely billed at the end of every month. So averaging the people who pay with cash or their debit card with the people who use the charge card or their credit card will result in a collection period of 16 days.
After doing some research we concluded that the online book company would have the balance sheet and financial data of column A.
