Segovia Produce Limited uses 800 wood crates a month to handle their produce. Crates are purchased from MillWood, Inc. at a cost of $10 each. Segovia's annual carrying cost is estimated as 35 percent of the purchase price per crate. Costs of placing an order with MillWood are estimated to be $28 per order. Currently the purchasing manager orders the crates once a month. How much could the firm save annually in ordering and carrying costs by using the EOQ instead? (25 points)
