EOQ is computed by:

$$ rac{{2D}}{{Ci}}$$
$$ rac{{Ci}}{{100}}$$
$$sqrt { rac{{2D{C_0}}}{{Ci}}} $$
$$ rac{D}{{100}}$$

The correct answer is C.

Economic order quantity (EOQ) is the optimal quantity of an item to order at a time in order to minimize total inventory costs. It is calculated by the following formula:

$$EOQ = \sqrt {\frac{{2D{C_0}}}{{Ci}}} $$

where:

  • $D$ is the annual demand for the item
  • $C_0$ is the fixed cost of placing an order
  • $C_i$ is the carrying cost per unit per year

Option A is the formula for the economic production quantity (EPQ), which is the optimal quantity of an item to produce at a time in order to minimize total production costs.

Option B is the formula for the carrying cost per unit per year.

Option D is the formula for the ordering cost per order.
