- The Jacob Textile Company is contemplating future of one of its plants located in Laguna. Three alternative decisions are being considered: (1) Expand the plant and produce lightweight, durable materials for possible sales to schools, a market with little local competition; (2) maintain the status quo at the plant, continuing production of textile goods that are subject to heavy local competition; or (3) sell the plant now. If one of the first two alternatives is chosen, the plant will still be sold at the end of the year. The amount of profit that could be earned by selling the plant in a year depends on local market conditions. The following payoff table describes this decision situation.States of Nature
