Answer:
111 pounds
Step-by-step explanation:
The number of pounds Cynthia should order each day can be calculated as follows
Calculation
Standard deviation = 20
Mean = 100
Cost of actual utilization = 8-3 = 5
Cost of Under utilization = 4-2 = 2
Probability of sale = Co/(Cu+Co)
Probability of sale = 5/(5+2)
Probability of sale =0.714
Z score at above probability = z = 0.57
hence cynthia should order= mean+z*standard deviation
Order = 100+0.57*20
Order = 111.4 or 111 pounds
