The Trim-Look Company makes several lines of skirts, dresses, and sport coats. Recently, a consultant suggested that the company reevaluate its South islander line and allocate its resources to products that would maximize contribution to profits and to overhead. Each product requires the same polyester fabric and must pass through the cutting and sewing departments. The following data were collected for the study.

Product Cutting Sewing Material (yd)
Skirt 1 1 1
Dress 4 3 1
Sport cost 6 6 4
The cutting department has 100 hours of capacity, sewing has 150 hours of capacity, and 60 yards of material are available. Each skirt contributes $8 to profits and overhead, each dress, $16 ; and each sport coat, $40.
