Answer:
170
Step-by-step explanation:
Assuming no safety stock is used, the reorder point (ROP) can be given by:
ROP = lead time x average daily demand.
The lead time is 5 days.
Average daily demand (ADD) is given by:
![ADD = (10,200)/(300) \\ADD = 34](https://img.qammunity.org/2020/formulas/business/college/3kvnw7mlqfcyuhx0tus5zqfmoqgjjjjvo7.png)
Therefore, the reorder point is:
![ROP = 34*5\\ROP = 170](https://img.qammunity.org/2020/formulas/business/college/hmfaaifw6r1yzrgm8z58e77unvigze95pj.png)
This means that Duncan's Stationery Shop should not let inventory fall under 170 binders in order to meet their average daily demand.
