Answer:
a. 320 units
b. $1,920
Explanation:
EOQ = √ 2 × Annual Demand × Ordering Cost per Order / Holding Cost per unit
= √ (2 × 3,000 units × $102.40 / ($30 × 20%))
= 320 units
total inventory cost = ordering cost + holding cost
= 3,000 units/ 320 units × $102.40 + 320 units/ 2 × ($30 × 20%
= $960 + $960
= $1,920
