Answer: 4 weeks
Explanation:
The following can be gotten from the question:
Weekly demand = 100 units
Since there are 52 weeks in a year, therefore, annual demand will be:
= 100 × 52 = 5200 units
Order quantity = 400 units
Total orders = 5200 / 400 = 13
The time between orders in weeks will then be:
= 52 / 13
= 4 weeks
