Q 18: A company is using the Economic Order Quantity (EOQ) model to manage its inventories. Suppose its annual demand doubles, while the ordering cost per order and inventory holding cost per unit per year do not change. What will happen to the total annual variable cost? The annual variable cost includes the annual ordering cost and annual inventory holding cost?

a) It doubles.

b) It increases by 41.42%.

c) It remains the same.

d) The impact depends upon the value of the ordering cost.

e) It quadruples (increases by 400%).

Q 19: The annual demand for an item is 2400 units. The inventory holding cost is $ 6.00 per unit per year. The demand is continuous and constant, that is, 200 units/month. The item is purchased in two lots. The size of the first lot is 1600 units and the size of the second lot is 800 units. Find the total annual cost of holding inventory.

Q 20: A manufacturing company sells its products directly to customers and operates 5 days a week, 52 weeks a year. The production department of this company can produce at the rate of 60 units per day. The setup cost for a production run is $ 125.00. The cost of holding is $ 4.00 per unit per year. The demand for the item is continuous and constant and is 3,900 units per year. (Note: The demand occurs only when the company is operating, that is, 5 days a week for 52 weeks). Find the optimum number of units to be produced in one batch (economic production quantity). Round the number to nearest integer.
