Answer: - According to given data
Average daily demand = 30 packages, Standard deviation = 4 packages
Annual demand = 300 days * 30 packages = 9000 packages
Cost price = $12, Ordering cost = $9 and Holding cost = 2%*cost = $0.24
Lead time = 4 days, Service level = 96% = z value = 1.75
a) Optimal order quantity = √2*D*S/H
= √2*9000*$9/$0.24 = 821.5 ~ 822 packages
b) Reorder point = demand during lead time + safety stock
Average demand during lead time = 30 packages *4 days = 120 packages
Safety stock = z * standard deviation of demand * √L
= 1.75*4*√4 = 14
Reorder point = 120 packages + 14 packages = 134 packages
