A small manufacturing plant makes three types of inflatable boats: one-person, two-person, and four-person models. Each boat requires the services of three departments, as listed in the table. The cutting, assembly and packaging departments have available a maximum of 380, 330 and

120 labor-hours per week, respectively.
