Consider the following decision problem. A company sells three different products: laptops, PCs, and tablets. The company want to decide how many laptops, PCs, and tablets to produce next quarter to maximize their total net profit from selling these products. The net profit associated with selling: a laptop is $800, a PC is $1000, and a tablet is $300. Each laptop costs $500 to produce, each PC costs $650 to produce, and each tablet costs $200 to produce. Total cost associated with producing all the products (laptops, PCs and tablets) to be sold next quarter cannot exceed $180,000. The market research shows that the company can sell at most 50 PCs and at most 100 tablets.
