The American Business College offers undergraduate and graduate courses, and post-grad seminars. Student demand makes it necessary to offer at least 35 undergraduate and 18 graduate courses, and 5 post-grad seminars in the upcoming semester. Faculty contracts dictate that the total number of courses and seminars must be at least 65. Qualified faculty are available to teach a maximum of 10 post-grad seminars. Undergraduate courses cost the college $3,650 in faculty wages, each graduate course costs $4,100, and each seminar costs $3,600.
