The port and Customs authorities at Cape Town harbour claim that imported textile consignments are cleared within an average of 72 hours of the goods being offloaded from a vessel. A local textile importer is not convinced of this, and believes that the average clearance time is much longer. He analysed documents of 46 recent consignments and found that the average clearance time was 75.9 hours. Assume a population standard deviation of 18 hours and that clearance time is approximately normally distributed.

Acaterer knows he will need 60, 50, 80, 40 and 50 dinner napkins on five successive evenings. he can purchase new napkins initially at 25 cents each, after which he can have dirty napkins laundered by a fast one-day laundry service (i. e., dirty napkins given at the end of the day will be ready for use the following day) at 15 cents each, or by a slow two-day service at 8 cents each or both. the caterer wants to know how many napkins he should purchase initially and how many dirty napkins should be laundered by fast and slow service on each of the days in order to minimize his total costs. formulate the caterer’s problem as a linear program as follows (you must state any assumptions you make): a. define all variables clearly. how many are there? b. write out the constraints that must be satisfied, briefly explaining each. (do not simplify.) write out the objective function to be minimized. (do not simplify.)
