Answer:
$4.00
Step-by-step explanation:
The cost of purchasing 1000 units per year is computed thus:
the annual cost of purchase=annual demand*cost per unit
annual demand=1000
cost per unit=$20
the annual cost of purchase=1,000*$20
the annual cost of purchase=$20,000
The cost of carrying or holding the inventory for one year is 20% of cost of purchase
Annual holding cost=20%*$20,000
Annual holding cost=$4,000
the unit inventory holding cost=annual holding cost/annual demand
the unit inventory holding cost=$4,000/1000
the unit inventory holding cost=$4.00
