Barry's hardware store carries 20 different types of ladders. Some are used for industrial purposes and are quite expensive. Others, intended for household use only, are very inexpensive. Barry has given each ladder an item number. The following table shows each ladder by item number, the demand in units for the year, and the average selling price for each ladder. Ordering cost is estimated to be $100 per order, and carrying cost is expected to be 7.5% of the selling price per year. Stockout cost is expected to be 200% of the price of the ladder, which includes the loss of current and future sales. What inventory policies do you recommend for the different types ofladders?
