A discussion with Morgana, the controller, brings to light two possible explanations. She informs you that the industry gross profit percent in the retail drug industry declined fairly steadily for three years, which accounts for part of the decline. A second factor was the declining percent of the total volume resulting from the pharmacy part of the business. The pharmacy sales represent the most profitable portion of the business, yet the competition from discount drugstores prevents it from expanding as fast as the non$-$drug items such as magazines, candy, and many other items sold. Morgana feels strongly that these two factors are the cause of the decline.$$ The following additional information is obtained from independent sources and the client$$s records as a means of investigating the controller$$s explanations:
