Jackson Mint produces collectible plates. It has recently contracted with the estate of well-known artist, Skip Gunther, to produce a series of five commemorative plates bearing copies of the artistâ€™s most famous pictures. The plates will be sold by subscription at a cost of $275 plus shipping and handling for the entire five-plate series. Jackson estimates the cost of producing each plate in the series at $12.50 plus a $9.75 royalty that Jackson has agreed to pay the Gunther estate. Jackson intends to mount a $175,000 nationwide advertising campaign promoting these plates as a â€œlimited editionâ€; that is, Jackson will specify the number of plates it will produce and limit production to that amount. Any unsold plates will be destroyed. Based on its previous experience with such products, Jackson estimates that customer demand for the series will be approximately normally distributed, with a mean of 1800 and a standard deviation of 250. If Jackson has more subscribers than plate series, it will refund subscribersâ€™ money with a note explaining that the series has been oversubscribed. Reasoning that the unsatisfied customers will be more willing to subscribe to Jacksonâ€™s future offerings, it estimates that each unsatisfied customer will earn the company an average of $40 in discounted future profits. a. What is the optimal number of Skip Gunther plate series Jackson should produce? b. What expected profit or loss will Jackson earn if it follows the production policy found in part (a)? c. Comment on any assumptions you made to solve this problem.
