(**) Average weekly demand for free-range dog biscuits is 80 bags per week, with a standard deviation of 16 bags. Ollah uses a continuous inventory review system to manage inven- tory of the biscuits. Ollah wants to set the reorder point high enough that there is only a 5% chance of running out before the next order comes in. Assuming that the lead time is a constant 2 weeks, what should the reorder point be?

### Inventory Management Problems

**Problem 10:**  
Suppose the supplier for workbenches at KraftyCity ensures that the lead time is consistently 3 weeks, with no variability. Recalculate the reorder point using the demand and service level data from problem 9. Determine if the reorder point is higher or lower and explain the reasoning.

**Problem 11:**  
Ollah’s Organic Pet Shop sells about 4,000 bags of free-range dog biscuits annually. The fixed ordering cost is $15, and the annual holding cost per bag is $2. Calculate the economic order quantity (EOQ) for the biscuits.

**Problem 12:**  
If Ollah decides to order 200 bags at a time, what would the total ordering and holding costs for the year be? For this analysis, do not include safety stock when calculating holding costs.

**Problem 13:**  
The average weekly demand for free-range dog biscuits is 80 bags, with a standard deviation of 16 bags. Utilizing a continuous inventory review system, Ollah aims to set the reorder point so there’s only a 5% chance of stockout before the next order arrives. With a lead time of 2 weeks, calculate the appropriate reorder point.

**Problem 14:**  
Ollah opts for a periodic review system to manage the inventory of free-range dog biscuits, checking stock levels weekly. With the same demand and lead time characteristics as in problem 13, and a 95% service level, determine the restocking level. Note: The standard deviation of weekly demand is 16, and the standard deviation of demand over 3 weeks calculates to ≈28.

**Problem 15:**  
Ollah’s Organic Pet Shop sells bags of cedar chips for pet bedding or snacking.
