(EOQ calculations) A downtown bookstore is trying to determine the optimal order quantity for a popular novel just printed in paperback. The store feels that the book will sell at four times its hardback figures. It would, therefore, sell approximately 3,000 copies in the next year at a price of $1.50. The store buys the book at a wholesale figure of $1. Costs for carrying the book are estimated at $0.25 a copy per year, and it costs $30 to order more books. a. Determine the EOQ. b. What would be the total costs for ordering the books 1, 4, 5, 10, and 15 times a year? c. What questionable assumptions are being made by the EOQ model? a. What is the economic order quantity (EOQ)? copies (Round to the nearest whole number.) b. What would be the total costs for ordering the books one time a year? $ (Round to the nearest dollar.) What would be the total costs for ordering the books four times a year? $ (Round to the nearest dollar.) What would be the total costs for ordering the books five times a year? (Round to the nearest dollar.) What would be the total costs for ordering the books 10 times a year? (Round to the nearest dollar.) What would be the total costs for ordering the books 15 times a year? (Round to the nearest dollar.) c. What questionable assumptions are being made by the EOQ model? (Select all that apply.) A. Independent orders. B. A constant unit price. C. Constant carrying costs. D. Constant or uniform demand. E. Instantaneous delivery. F. Constant ordering costs
