Answer:
A) 100
Explanation:
total sales 3,600 units
cost per unit $200
cost of placing order $40
holding cost $20 per year
working days 360 per year
lead time 5 days
If Mark orders 200 units each time, his average inventory ?
daily sales = total sales / working days = 3,600 / 360 = 10 units per day
number of orders per year = 3,600 / 200 = 18
Mark places one order every = 360 days / 18 orders = 20 days
average inventory = (200 units / 20 days) x 10 days = 100
I assume that mark has some type of safety stock that allows him to hold enough inventory to cover for the 5 day lead time.
