Answer:
the Annual inventory cost is $800.
Step-by-step explanation:
The computation of the total annual inventory cost is given below:
Demand, D = 4000
Order cost, S = $ 20
Holding cost, H = $ 4
So,
EOQ = sqrt(2 ×D × S ÷ H)
= sqrt(2 × 4000 × 20 ÷ 4)
= 200
Now
Annual inventory cost = Annual setup cost + Annual holding cost
= (D ÷ Q × S) + (Q ÷ 2 × H)
= (4000 ÷ 200 × 20) + (200 ÷ 2 × 4)
= 400 + 400
= $800
hence, the Annual inventory cost is $800.
