Answer:

c. 246 units

Explanation:

Daily demand, d = 20 units

Service Level = 95 % = 0.95. Z (according to Standardized Normal Curve) = 1.65

Average Lead Time, LT-bar = 9 days

Standard deviation of Lead Time, σLT = 2 days

Reorder Point = Expected Demand during Lead time + Safety Stock

Reorder Point = d*LT-bar + z*d*σLT

Reorder Point = (20*9) + (1.65*20*2)

Reorder Point = 180 + 66

Reorder Point = 246 units
