Answer:
240 units
Explanation:
The Economic Order Quantity (EOQ) is the order quantity that minimizes annual ordering and holding costs. It is calculated as :
EOQ = â(2 x annual demand x cost per order) á holding cost per unit
therefore,
EOQ = â(2 x 1,000 x 12 x $6) á $2.50
    = â57,600
    = 240 units
Thus, 240 units would be the order quantity that minimizes annual ordering and holding costs
