Answer:
B) greater than $30 but less than $40
Explanation:
the options are missing:
A) less than or equal to $30
B) greater than $30 but less than $40
C) greater than $40 but less than $50
D) greater than $50
we must first calculate safety stock = (Z-score x √lead time x standard deviation of demand) + (Z-score x standard deviation of lead time x average demand)
- Z-score for 98% confidence level = 2.326
- standard deviation of demand = 30
- √lead time = √5 = 2.23607
- we are not given any standard deviation of lead time, so we can assume that it is 0
safety stock = (2.326 x √2.23607 x 30) + (2.326 x 0 x 300) = 156.03 ≈ 156 units
the annual holding cost of 156 units = 156 x $0.25 = $39
