A bаkery shоp is trying tо decide hоw mаny doughnuts (dozens) to mаke each day.  The cost to make a dozen doughnuts is $5.00.  If sold that day, the doughnuts can be sold for $10.00 per dozen.  On the other hand, excess doughnuts must be sold at the day-old discount price of $4.00 per dozen.    Based on past experience, the manager estimates the probabilities for demand shown below.       Demand (doz).       Probability                   20                       .10             21                       .15             22                       .30             23                       .20             24                       .15              25                         .05 Calculate the optimal number of doughnuts (dozens) to make each day using the service probability ratio method. Type in a few calculations and results to show your solution method and indicate the optimal quantity that you have determined.  (Note: it is not necessary to type in all the calculations and details.)
