A. The Walters manufacturing Company has three types of sheds that it produces (Type 1, Type 2, and Type 3). Producing each type of shed requires different amounts of time for stamping, painting, and packaging (see table). The Walters Company has a maximum of 3200 hours for stamping, 1700 hours for painting and 1300 hours for packaging during each production cycle.
