Hammonds Corporation is trying to decide between two alternate order plans for its inventory of a certain item. Irrespective of the plan to be followed, demand for the item is expected to be 1,000 units annually. Under Plan A: order costs would be $ 40 per order and inventory holding costs (carrying cost) would be $100 per unit per annum. Under Plan B order costs would be $30 per order, while holding costs would be 20% of unit cost which is $480. Determine: i. the economic order quantity for EACH plan ii. total inventory cost for EACH plan iii. hence, indicate which plan would be better for the company
