3C. White Valley Ski Resort is planning the ski lift operation for its new ski resort. 03 Management is trying to determine whether one or two lifts will be necessary, each lift can accommodate 250 people per day. Skiing normally occurs in the 14 week period from December to April, during which the lift will operate seven days per week. The first lift will operate at 90% capacity if economic conditions are bad, the probability of which is believed to be about 0.3. During normal times the first lift will be utilized at 100% capacity and the excess crowd will provide 50% utilization of the second lift. The probability of normal times is 0.5. Finally if times are really good, the probability of which is 0.2, the utilization of the second lift will increase to 90%. The equivalent annual cost of installing a new lift, recognizing the time value of money and the lift's economic life is $ 50,000. The annual cost of installing two lifts is only S 90,000 if both are purchased at the same time. If used at all each lift costs $ 2,00,000 to operate, no matter how low or high its utilization rate. Lift tickets cost $ 20 per customer per day. Draw the decision tree and determine whether the resort should purchase one lift or two
