Answer: $4,800
Step-by-step explanation:
First find the Annual holding cost:
= Average inventory * Cost of holding a unit
= 500/2 * 1 * 12 months
= $3,000
Then find the Annual ordering cost:
= Expected units to be sold/ Units ordered * Ordering cost
= 9,000/500 * 100
= $1,800
Annual Inventory cost = Annual holding cost + Annual ordering cost
= 3,000 + 1,800
= $4,800
