what is the reoder point (correct answer is 1119.5)... i dont know how to calculate it.

Information Flag question Given the following information, formulate an inventory management system. The item is demanded 50 week a year. Item cost $12.00 Average demand 525 per week Order cost $300.00 Standard deviation of 30 per week Annual holding cost (6) 25 % of item cost Annual demand 26,250 Service probability Formulas for inventory control are provided below. weekly demand Lead time 2 week 9596 Inventory control Single-period model. Cumulative probability of not selling the last unit. Ratio of marginal cost of -model. Total annual cost for an order Q. a per-unit underestimating demand and marginal cost of cost C setup costs, and per-unit holding cost H. overestimating demand C TC=DC+SH PS CE+ O-model. Optimal (or economie) order quantity. Q-model. Reorder point R based on average daily 2DS demand d and lead time in days. Q. RdL H D-model. Reorder point providing a safety stock of 20 Average daily demand over a period of days. R=dL + 20 d = Standard deviation of demand over a period of days Standard deviation of a series of independent demands. En(d, -d) = V0 +0,*+ +0, 0 O-model. Safety stock calculation P-model. Safety stock calculation SS=0 P-model. Optimal order quantity in a fixed period P-model. Standard deviation of a series of independent system with a review period of 1 days and lead time of demands over the review period of T and lead time of L. days.
