the annual carrying cost is $0.63 per pound. The ordering cost for filling is $4,500, and the annual
carrying cost is $0.55 per pound.

Diamant Foods Company produces various food products, including a line of candies. One of its
most popular candy items is Divine Diamonds, a bag of a dozen individually wrapped diamond-
shaped candies made primarily from a blend of dark and milk chocolates, macadamia nuts, and
a blend of heavy cream fillings. The item is relatively expensive, so Diamant Foods produces it
only for its eastern market, encompassing urban areas such as New York, Atlanta, Philadelphia,
and Boston. The item is not sold in grocery or discount stores but mainly in specialty shops and
specialty groceries, candy stores, and department stores.
Diamant Foods supplies the candy to a single food distributor, with several warehouses on the
East Coast. The candy is shipped in cases of 60 bags per case. Diamonds sell well, despite being
expensive, at $9.85 per bag (wholesale). Diamant uses high-quality, fresh ingredients and does
not store large candy stocks in inventory for very long periods.
Diamant's distributor believes that demand for the candy follows a seasonal pattem. It has
collected demand data (i.e., cases sold) for Diamonds from its warehouses and the stores it
supplies for the past three (3) years, as follows:

The distributor must hold the candy inventory in climate-controlled warehouses and be careful
handling it. The annual carrying cost is $116 per case. Diamonds must be shipped a long distance
from the manufacturer to the distributor, and to keep the candy as fresh as possible, trucks must
be air-conditioned, shipments must be direct, and shipments are often less than a truckload. As
a result, the ordering cost is $4,700.
Diamant Foods makes Diamonds from three (3) primary ingredients it orders from different
suppliers: dark and milk chocolate, macadamia nuts, and a special heavy cream filling. Except for
its unique shape, a Diamond is almost like a chocolate truffle. Each Diamond weighs 1.2 ounces
and requires 0.70 ounce of blended chocolates, 0.50 ounce of macadamia nuts, and 0.40 ounce
