Question

The Carlson Department store suffered heavy damage when a hurricane struck on August 31. The store was closed for four months (September through December), and Carlson is now involved in a dispute with its insurance company about the amount of lost sales during the time the store was closed. Two key issues must be resolved (1) The Amount of sales Carlson would have made if the hurricane had not struck and (2) whether Carlson is entitled to any compensation for excess sales due to increased business activity after the storm. More than $8 Billion in federal disaster relief and insurance money came into the country, resulting in increased sales at department stores and numerous other businesses.

Table 6.18 gives Carlson's sales data for the the 48 month preceding the storm. Table 6.19 reports total sales for the 48 months preceding the storms for all department stores in the country , as well as total sales in the country for the four months the Carlson's Department Store was closed.
