Question 5 2 pts The average demand for a particular part is 49 units a day. The unit cost of the part is $49. It costs $38 to place an order, and the inventory carrying cost per unit per year is 18% of the unit cost. Assume 250 working days a year. How many orders should be placed per year in order to satisfy demand and minimize total inventory cost? Numbers only, keep 3-decimal if not exact, either round up or down is ok. Question 6 2 pts The demand for a medical equipment is uncertain and follows a normal distribution. Its average daily demand is 27 units, with a daily standard deviation of 5 units. It costs $64 to place an order, and it takes 3 weeks to receive the order. The equipment requires a 95% service level, or a 95% probability of not-stocking-out. What would be the safety stock level to satisfy the required 95% service level? Note that z = normsinv(0.95) = 1.64. Numbers only, keep 3-decimal if not exact, either round up or down is ok
