A) EOQ = 208.56 units

B) Average inventory = 104.28 units

C) Optimum number of order = 28.76 times

Explanation:

Economic order quantity is the order quantity that minimizes the balance of ordering and carrying cost.

Economic order quantity = √2 * 29 * 6,000/8=208.56 units

Average inventory = Minimum stock level + Order quantity/2

minimum stock level is not given, hence

Average inventory = 208.56/2 = 104.28 units

Optimum number of order

Optimum number of order = Demand / order quantity

= 6000/208.56 = 28.76 times.

EOQ = 208.56 units

B) Average inventory = 104.28 units

C) Optimum number of order = 28.76 times
