A manager must decide on the mix of products to produce for the coming week. Product A requires three minutes per unit for molding, two minutes per unit for painting, and one minute per unit for packing. Product B requires two minutes per unit for molding, four minutes per unit for painting, and three minutes per unit for packing. There will be 600 minutes available for molding, 600 minutes for painting, and 420 minutes for packing. Both products have profit contributions of $1.50 per unit. Formulate this problem as a linear programming problem. (You do not need to solve this problem). If you were solving this problem using Solver, what would you put in the target cell, changing cells?
