QUESTION 2: B. A stationery wants to order sets of tree decorations in mid-November. Tree decorations are purchased for 325 TL, and sold for 542 TL. Due to the high ordering cost, only one procurement will be made. The manager of the stationery has estimated that the sales will be normally distributed with a mean of 1,482,700 sets, and a variance of 932,750 sets. If the stationery cannot satisfy a customer's demand, a loss of goodwill of 150 TL will be incurred. After New Year, it is unlikely that any more tree decorations will be sold, and it will cost 10 TL to keep each set in inventory until the next season. How many sets of tree decorations should the stationery order in mid-November?
