The following table shows the staffing requirements and the associated costs (in thousand dollars) for a local firm. The firm requires workers to work for three consecutive seasons and to take the following season off. Formulate a linear program (ignoring the integrality constraints) to minimize the total (annual) cost of workers while satisfying the staffing requirements. Do not solve the problem. Fall Winter Spring Summer Required number of workers 41 49 31 30 Seasonal cost per worker 15 21 24 12
