The curve below represents the holding (carrying) cost and the ordering cost in a particular inventory situation in which all of the EOQ assumptions are met. The optimal (minimum cost) quantity is found to be 200 units. if 250 units were ordered each time an order was placed (instead of the EOQ), the total annual holding cost a. would be higher than the total annual holding cost for the EOQ. b. would be lower than the total annual holding cost for the EOQ c. would be the same as total annual holding cost for the EOQ. If 250 units were ordered each time an order was placed (instead of the EOQ., the total annual ordering cost a. would be higher than the total annual ordering cost for the EOQ. b. would be lower than the total annual ordering cost c. would be the same as total annual ordering cost for the EOQ. Suppose the holding cost per unit per year increases while all other costs and the annual demand remain constant. The total annual ordering cost for the optimal solution would a. increase. B. decrease. c. not change
