Click the icon to view the table of z values. a. What is the economic order quantity for the biscuits? The EOQ is. (Enter your response rounded to the nearest whole number.) b. Suppose Ollah decides to order 340 bags at a time. What would the total ordering and holding costs for the year be? (For this problem, don't consider safety stock when calculating holding costs.) The total ordering and holding costs are $. (Enter your response rounded to the nearest dollar.) c. Average weekly demand for free-range dog biscuits is 86 bags per week, with a standard deviation of 6 bags. Ollah uses a continuous inventory review system to manage inventory of the biscuits.

Suppose Ollah decides to use a periodic review system to manage the free-range dog biscuits, with the vendor checking inventory levels every week. Under this scenario, what would the restocking level be, assuming the same demand and lead time characteristics listed in part c. and same 99% service level? (Note that because the standard deviation of weekly demand is 6, basic statistics tells us the standard deviation of demand over 5 weeks will be 13.) The restocking level is bags.
