Answer: As no specific information is mentioned in the question, we will find the unit cost by dividing the total inventory cost by the annual demand, assuming the total inventory cost includes, the annual inventory holding cost, annual inventory ordering cost, and the annual purchasing cost.
Step 1: Find Economic Order Quantity (EOQ)
Let D = Annual Demand = 16428 Units
O = Ordering Cost Per Order = 517 $
H = Holding Cost Per Unit Per Annum = 0.27 X 20 = 5.4 $
P = Purchase Price Per Unit = 20 $
Q = EOQ = SQRT [( 2 X D X O) / H]
= SQRT [ ( 2 X 16428 X 517) / 5.4]
= SQRT ( 3145657.78)
= 1773.60 Units (Rounded to 2 decimal places)
Step 2: Find the total inventory cost =
Total Inventory Cost = ( Q / 2) H + (D / Q) O + P X D
= [(1773.60 / 2 ) 5.4 ]+ [(16428 / 1773.60) 517] + [20 X 16428]
= 4788.72 + 4788.72 + 328560
= 338137.44 $
Step 3: Find Unit Cost
Unit Cost = Total Inventory Cost / D = 338137.44 / 16428 = 20.5830 $ (Rounded to 4 Decimal Places)
