Answer:
74 units and 90 units.
Step-by-step explanation:
So, we have the demand for the first six months, K1 = 600 units = 600 units/ 6months = 100 units; the demand for the second six months, K2 = 900 units = 900/6 = 150 units; holding cost,J = $2 per unit ; process cost, P = $55 per order.
The formula for determining an order size that will minimize the sum of ordering and carrying costs for each of the six-month periods is the Economic Order Quantity formula which is given below;
Economic Order Quantity = √[ (2 × K1 × P)/ J ].
(1). For the first six months;
Economic Order Quantity = √ [ ( 2 × 100 × 55)/ 2].
Economic Order Quantity = 74 units.
(2). For the second six months.
Economic Order Quantity = √ [ ( 2 × 150 × 55)/ 2].
Economic Order Quantity = 90 units.
