The answer is that, "Mary was conducting an experiment".
Mary has done the experiment by raising the price of cookies every week, and when her experiment finished, she concluded a result from her experiment about the price of cookies which is more profitable. So in daily life we do many experiments to get conclusion from them sometimes it takes more time some times less.
Answer:
a) safety stock = z-score x √lead time x standard deviation of demand
z-score for 99.9% = 3.29053
√lead time = √7 = 2.6458
standard deviation of demand = 3
safety stock = 3.29053 x 2.6458 x 3 = 26.12 ≈ 26 soaps
reorder point = lead time demand + safety stock = (7 x 16) + 26 = 138 soaps
EOQ = √[(2 x S x D) / H]
S = order cost = $10
D = annual demand = 16 x 365 = 5,840
H = $0.05
EOQ = √[(2 x $10 x 5,840) / $0.05] = 1,528.40 ≈ 1,528 soaps
b) total order costs per year = (5,840 / 1,528) x $10 = $38.22
total holding costs = (1,528 / 2) x $0.05 = $38.20
total annual ordering and holding costs = $76.42
