Dan McClure owns a thriving independent bookstore in artsy New Hope, Pennsylvania. He must decide how many copies to

order of a new book, Power and Self$-$Destruction, an expos$$ on a famous politician's lurid affairs. Interest in the book will be intense at first and then fizzle quickly as attention turns to other celebrities. The book's retail price is $$20,$ and the wholesale price is $$12.$ The publisher will buy back the retailer's leftover copies at a full refund, but McClure Books incurs $$4$ in shipping and handling costs for each book returned to the publisher. Dan believes his demand forecast can be represented by a normal distribution with a mean of $200$ and a standard deviation of $80.$
