Ling Li of Li​ Windows, Inc. is considering making a change in the material the firm uses for panes in its residential window line. The new material has a slight mirror attribute that assists in reflecting​ ultra-violet light and restricts the transmission of heat. The new material will raise the cost of a standard window by​$3.76. The current window is in the mature stage of the life cycle and with no​ modifications, Li has estimated that sales of the window line will be​ 240,000 units per year for the next 5 years with a probability of​ 0.3, and has a 0.70 probability of selling​180,000 units per year over the five years. The standard profit margin of a window unit is​ $45. With the new glass​ material, the selling price per unit can be increased by​ $5 (but with the added​cost, the net increase in profit margin ​=(($45plus​$5)minus​$3.76)​= $46.24). ​ However, Li estimates that the demand for the newly designed window will be​ 210,000 units with a probability of​ 0.6, and that there will be a 0.4 probability of sales of​ 150,000 units.
