The first edition hardcover of a new book by a popular writer has a demand which is normally distributed with an average of 5 million and a standard deviation of 1 million. The production and transportation costs per hardcover are $12, and the sale price in bookstores is $30. When the paperback version comes out, the hardcover books go on sale for $7.50. How many hardcovers should be produced? Group of answer choices
A. 6.00 million
B. 5.00 million
C. Approximately 5.84 million
D.Exactly 5.80 million
Answer: C (Approximately 5.84 million)
Rationale:
Selling of hardcover (S.P.) = $ 30
Cost Price of handcover (C.P.) = $ 12
Salvage Value of hardcover (S.V.) = $ 7.5
Underage Cost (Cu) = S.P. - C.P.
Underage cost (Cu) = $ 30 - $ 12
Underage Cost (Cu) = $ 18
Overage cost (Co) = C.P. - S.V.
Overage Cost (Co) = $ 12 - $ 7.5
Overage cost (Co) = $ 4.5
Service level = Cu/ (Cu+Co)
Service level = 18/ (18+4.5)
Service level = 0.8
*Use service level table or Z-table to find value of Z at 0.8
Value of Z = 0.84
Given,
Mean demand (d) = 5 million
Standard deviation (s) = 1 million
Optimal demand = d + (Z × s)
Optimal demand = 5 + (0.84 × 1)
Optimal demand = 5.84 million
Therefore, 5.84 million hardcovers should be produced.
