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 $150. Requirements 1. Calculate Garden Tech's EOQ for the rotor blade part. 2. Calculate Garden Tech's annual relevant ordering costs for the EOQ calculated in requirement 1. 3. Calculate Garden 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 Garden Tech's reorder point for the rotor blade part.
