The correct answer is A. 566 units.
The economic order quantity (EOQ) is the order quantity that minimizes the total annual cost of ordering and carrying inventory. It can be calculated using the following formula:
EOQ = â(2DC/h)
where:
D = annual demand in units
C = ordering cost per order
h = carrying cost per unit per year
In this case, we are given the following information:
D = 8000 units
C = 30
h = 0.075
Substituting these values into the formula, we get:
EOQ = â(2800030/0.075) = 566 units
Therefore, the economic order quantity is 566 units.
Option B is incorrect because it is the order quantity that minimizes the ordering cost. Option C is incorrect because it is the order quantity that minimizes the carrying cost. Option D is incorrect because it is the order quantity that minimizes the total annual cost of ordering and carrying inventory.
