Store 1 was established first and was built at a lower cost than were Stores 2 and 3. This lower cost results in less depreciation expense for Store 1. Store 2 follows a policy of minimizing both costs and sales prices. Store 3 follows a policy of providing extensive customer service and charges slightly higher prices than the other two stores. Top management of Drexel-Hall is considering closing Store 3. The three stores are close enough together that management estimates closing Store 3 would cause sales at Store 1 to increase by $76,000, and sales at Store 2 to increase by $104,000. Closing Store 3 is not expected to cause any change in common fixed costs. Compute the increase or decrease that closing Store 3 should cause in: a. Total monthly sales for Drexel-Hall stores. b.
