Hi-tech, inc., is a computer training company serving metropolitan toronto, canada. the firm contracts a group of part-time instructors to teach a variety of courses concurrently at its downtown location. while demand is so high that any class offered will be filled immediately, hi-tech is looking at only two courses at this time: introduction to computers (itc) and creation of web pages (cwp). each itc class requires 7.5 hours of preparation/instruction time and contributes a profit of $720, whereas each cwp class calls for only 3 hours and contributes $300. available time for these two courses is limited to 56 hours a day. there is a restriction on the maximum number of trainees that can be efficiently handled. more specifically, at most 100 students can be accommodated on a daily basis without putting a strain on the facility and support staff. additionally, each course has a class size limit - 6 for itc and 12 for cwp. hi-tech would like to maximize the daily total profit from both courses so that it could offer certain other courses on a "goodwill" basis. formulate an ailp for management to decide how many classes should be scheduled for each subject daily.
