State University Business School (SUBS) offers several degrees, including Bachelor of Business Administration (BBA). The new dean believes in using cost accounting information to make decisions and is reviewing a staff-developed income statement broken down by the degree offered. The dean is considering closing down the BBA program because the analysis, which follows, shows a loss. Tuition increases are not possible. The dean has asked for your advice. If the BBA degree program is dropped, school administration costs are not expected to change, but direct costs of the program, such as operating costs, building maintenance, and classroom costs, would be saved. There will be no other changes in the operations or costs of other programs.
