Widgetco manufactures widgets at two factories, one in Memphis and one in Denver. The Memphis factory can produce as many as 150 widgets per day, and the Denver factory can produce as many as 200 widgets per day. Widgets are shipped by air to customers in Los Angeles and Boston. The customers in each city require 130 widgets per day. Because of the deregulation of airfares, Widgetco believes that it may be cheaper to first fly some widgets to New York or Chicago and then fly them to their final destinations. The costs of flying a widget are shown below. Widgetco wants to minimize the total cost of shipping the required widgets to its customers.

- Seas Beginning sells clothing by mail order. An important question is when to strike a customer from the companys mailing list. At present, the company strikes a customer from its mailing list if a customer fails to order from six consecutive catalogs. The company wants to know whether striking a customer from its list after a customer fails to order from four consecutive catalogs results in a higher profit per customer. The following data are available: If a customer placed an order the last time she received a catalog, then there is a 20% chance she will order from the next catalog. If a customer last placed an order one catalog ago, there is a 16% chance she will order from the next catalog she receives. If a customer last placed an order two catalogs ago, there is a 12% chance she will order from the next catalog she receives. If a customer last placed an order three catalogs ago, there is an 8% chance she will order from the next catalog she receives. If a customer last placed an order four catalogs ago, there is a 4% chance she will order from the next catalog she receives. If a customer last placed an order five catalogs ago, there is a 2% chance she will order from the next catalog she receives. It costs 2 to send a catalog, and the average profit per order is 30. Assume a customer has just placed an order. To maximize expected profit per customer, would Seas Beginning make more money canceling such a customer after six nonorders or four nonorders?Fairway Inc. makes custom golf clubs. They are manufactured in 3 plants in Denver, Phoenix, and Dallas. They are then shipped to distribution centers in Sacramento, Salt Lake, Chicago, Albuquerque, and New York. Since shipping costs are a major expense, management requires an analysis to determine the optimal shipping routes and quantities shipped along those routes. Each plant has a maximum production capacity and each distribution center has a demand that must be satisfied. You must determine how many clubs to send along each route, staying within plant capacity, meeting demand, for the lowest total shipping cost. Shipping Costs per route Plants Sacramento Salt Lake Chicago Albeq New York Capacity Denver $10 $8 $6 $5 $4 310 Phoenix $6 $5 $4 $3 $6 260 Dallas $3 $4 $5 $5 $9 280 Demand 180 80 200 160 220 Number to ship from plant to warehouse: Plants Sacramento Salt Lake Chicago Albeq New York Total Shipped Denver Phoenix…The New England Cheese Company produces two cheese spreads by blending mild cheddar cheese with extra sharp cheddar cheese. The cheese spreads are packaged in 12-ounce containers, which are then sold to distributors throughout the Northeast. The Regular blend contains 75% mild cheddar and 25% extra sharp, and the Zesty blend contains 70% mild cheddar and 30% extra sharp. This year, a local dairy cooperative offered to provide up to 8500 pounds of mild cheddar cheese for $1.40 per pound and up to 2700 pounds of extra sharp cheddar cheese for $1.60 per pound. The cost to blend and package the cheese spreads, excluding the cost of the cheese, is $0.40 per container. If each container of Regular is sold for $2.20 and each container of Zesty is sold for $2.00, how many containers of Regular and Zesty should New England Cheese produce? Do not round your interim computations. If required, round your answers to the nearest whole number. Let R = number of containers of Regular Z =…

- Sunco Oil produces oil at two wells. Well 1 canproduce up to 150,000 barrels per day, and well 2 canproduce up to 200,000 barrels per day. It is possible toship oil directly from the wells to Sunco’s customersin Los Angeles and New York. Alternatively,Sunco could transport oil to the ports of Mobile andGalveston and then ship it by tanker to New Yorkor Los Angeles. Los Angeles requires 160,000 barrelsper day, and New York requires 140,000 barrels perday. The costs of shipping 1000 barrels betweenvarious locations are shown in the file P05_55.xlsx,where a blank indicates shipments that are not allowed.Determine how to minimize the transport costs inmeeting the oil demands of Los Angeles and New York.The town of Lexington purchases gasoline from three vendors to fuel its fleet of municipal vehicles. Each vendor delivers gasoline in 6,000 gallon quantities. Since vendors must deliver the fuel, a transportation fee (based on the distance the vendor must travel) is added to each delivery.

The mill will produce only Fabric 1 and Fabric 2 during the coming month. Each dobby loom can turn out 4.62 yards of either fabric per hour. Assume that there is a monthly demand of 16,000 yards of Fabric 1 and 12,000 yards of Fabric 2. Profits are calculated as 33¢ per yard for each fabric produced on the dobby looms. (a) Will it be possible to satisfy total demand? (b) In the event that total demand is not satisfied, the Scottsville Textile Mill will need to purchase the fabrics from another mill to make up the shortfall. Its profits on resold fabrics ordered from another mill amount to 20¢ per yard for Fabric 1 and 16¢ per yard for Fabric 2. How many yards of each fabric should it produce to maximize profits?
