Macromedia is a relatively new company that offers computer training seminars on a variety of topics. In the seminars each student works at a personal computer, practicing the activity that the instructor is presenting. To introduce themselves to potential students they have recently spent $6,000 to design, print and distribute brochures. The company is currently planning a two-day seminar on the use of Microsoft Excel in statistical analysis. The projected fee for the seminar is $300 per student. The cost of the conference room, instructor compensation, lab assistants, and seminar-specific promotion is $4800. Macromedia also rents computers for its seminars at a cost of $30 per computer per day.
