Answer:

a) EOQ = 36 units

b) Average Inventory=18 units

c) No of orders per year= 135 times

d) Ordering cost ($540 ) = Carrying cost ($540)

Step-by-step explanation:

The economic order quantity is the order size that minimizes the the balance of holding cost and ordering cost.

It is calculated using the formula below:

a) EOQ = √ 2×Co×D/Ch

Co- 4, Ch- 30 - D - 4, 860

EOQ = √ 2×4×4,860/30

= 36 units

b) Average Inventory = EOQ /2

= 36/2 = 18 units

c) No of orders per year = Annual demand/ EOQ

=4,860/36 = 135 times

d) At the EOQ, the holding cost = Ordering cost

Holding cost = holding cost per unit × Average inventory

= $30× 18 = $540

Annual ordering cost = ordering cost per unit × No of orders

= $4 × 135 = $540

Ordering cost ($540 ) = Carrying cost ($540)
