Problem 3 ) (12 points) a) Compute the multifactor productivity measure (output in sales dollars) for each week using the data provided below to produce chocolate bars. Assume 40-hour weeks and an hourly wage of $18. Overhead is 1.25 times the total weekly labor cost. Material cost is $48 per pound. Standard price to sell is $150 per unit. (10 points) b) What do the productivity figures suggest? (What is the trend?) (2 point) Problem 4) (12 points) Milk is stocked at a grocery store each week. At the end of each week, unsold milk price is reduced by 25% and the store can sell the unsold milk fully at this lower price. If weekly demand for milk is normally distributed with a mean of 200 gallons and standard deviation of 20 gallons, find the price for which a fresh gallon of milk sells. Assume that the store has a service level of 90% and purchases milk for \$3.1 per gallon
