The I-75 Carpet Discount Store in North Georgia stocks carpet in its
warehouse and sells it through an adjourning showroom. The store keeps
several brands and styles of carpet in stock. However, its biggest seller
is Super Shag carpet. The store wants to determine the optimal order size
and total inventory cost for this brand of carpet given an estimated
annual demand of 10,000 yards of carpet, an annual carrying cost of $0.75
per yard, and an ordering cost of $150. The store would also like to know
the number of orders that will be made annually and the time between
orders (i.e. the order cycle) given that the store is open every day
except Sunday, Thanksgiving day, Christmas day (which is not on a Sunday).
