Green Tech Company, which produces lawn mowers, purchases 22,065 units of a rotor blade part each year at a cost of $65 per unit. Green Tech requires a 20% annual rate of return on investment. In addition, the relevant carrying cost (for insurance, materials handling, breakage, and so on) is $6 per unit per year. The relevant ordering cost per purchase order is $155. Requirements 1. Calculate Green Tech's EOQ for the rotor blade part. 2. Calculate Green Tech's annual relevant ordering costs for the EOQ calculated in requirement 1. 3. Calculate Green Tech's annual relevant carrying costs for the EOQ calculated in requirement 1. 4. Assume that demand is uniform throughout the year and known with certainty so that there is no need for safety stocks. The purchase-order lead time is half a month. Calculate Green Tech's reorder point for the rotor blade part. Requirement 1. Calculate Green Tech's EOQ for the rotor blade part. Begin by selecting the formula used to calculate EOO. (D = Demand in units for one year, P = Ordering cost per purchase order, C = Carrying cost of one unit in stock, Q = Any order quantity)
