Answer:

D. 20 days

Explanation:

Daily usage rate: 50 kg each day

Order size: 1,000 kg

lead time: 4 days

Since the question just wants to know the length of an order cycle, all of the monetary information can be disregarded.

The company must maintain a stock, at the time of order, big enough to supply production during the lead time. Minimum stock should be:

[tex]Min = 50\frac{kg}{day} * 4\ days\\Min = 200 \ kg[/tex]

Therefore, the company must reorder when stock reaches 200 kg. The length of the order cycle is the number of days for the company to reach minimum stock added to the order lead time:

[tex]C = \frac{1000 - 200}{50} +4\ days\\C= 20\ days[/tex]
