Jane MacFarlane wants a weekly schedule for two business services, X and Y. Each ‘unit' of X delivered to customers needs one service package, while each unit of Y uses two of the packages, and Jane has a maximum of 80 packages available a week. Each unit of X and Y needs 10 hours of subcontracted work, and Jane has signed agreements with subcontractors for a weekly minimum of 200 hours and a maximum of 600 hours. Jane knows from market surveys that demand for Y is high, and she will have no trouble selling any number of units.
