13.26 County Hospital orders syringes from a hospital supply firm. The hospital expects to use 40,000 per year. The cost to order and have the syringes delivered is $800. The annual carrying cost is $1.90 per syringe because of security and theft. The hospital supply firm offers the following quantity discount pricing schedule.

QUANTITY PRICE
????0–9,999 $3.40
10,000–19,999 ?3.20
20,000–29,999 ?3.00
30,000–39,999 ?2.80
40,000–49,999 ?2.60
50,000+ ?2.40

1. What is the order quantity and total cost at each price point.

2. How would you advise the hospital?

3. Would your recommendation change if yearly demand went up to 45,000?

4. What is the reorder point for both demand levels if it takes 4 days for supplies to arrive.

5. Realistically demand for syringes is variable, and the daily demand is normally distributed at 105 a day with a standard deviation of 10. The lead time for restocking is still 4 days. If the hospital wants a service level of 99%, what is the reorder point? How much safety stock does this include?
