A bakery wants to determine how many trays of doughnuts it should prepare each day. Demand is normal with a mean of 5 trays and

standard deviation of 1 tray. If the owner wants a service level of at least 95%, how many trays should he prepare (rounded to the nearest whole tray)? Assume doughnuts have no salvage value after the day is complete.

Answer:

7 trays

Step-by-step explanation:

Given the \mu=5, \sigma=1, the z score is obtained using the formula:

z=\frac{x-\mu}{\sigma}

The z score value for a 95% interval is 1.645.

#Substitute our z value and solve for x:

z=\frac{x-\mu}{\sigma}\\\\1.645=\frac{x-5}{1}\\\\1.645+5=x\\\\x=6.645\approx7

Hence, the bakery must prepare 7 trays of  doughnuts .

Step-by-step explanation:

then you would -50 from both sides

280=40x

then you would divide both sides by 40 to isolate x

7=x

so that means it would take 7 weeks
