6. A firm produces four products: A, B, C. and D. Each unit of product A requires two hours of assembly, one hour of finishing, and P10 worth of in-process inventory. Each unit of product B requires 1 hour of assembly, 3 hours of finishing, and P5 worth of in-process inventory. Each unit of product of C requires 2.5 hours of assembly, 2.5 hours of finishing, and P2 worth of in-process inventory. Finally each unit of product D requires five hours of assembly, no finishing, and P12 worth of in-process inventory. The firm has 120,000 hours assembly time and 160,000 hours of finishing time available. In addition, not more than P1 million may be tied up in-process inventory. Each unit of product A returns a profit of P40; each unit of product B returns a profit of P24; each unit of product C returns a profit of P36; and each unit of product D returns a profit of P23. Not more than P20,000 units of product A can be sold; not more than 16,000 units of product C sold; any number of units of products B and D may be sold. However, at least 10,000 units of product D must be produced and sold to satisfy a contract requirement. The objective of the firm is to maximize the profit resulting from the sales of the four products.

- 4 Sunco processes oil into aviation fuel and heating oil. Itcosts $40 to purchase each 1,000 barrels of oil, which isthen distilled and yields 500 barrels of aviation fuel and 500barrels of heating oil. Output from the distillation may besold directly or processed in the catalytic cracker. If soldafter distillation without further processing, aviation fuelsells for $60 per 1,000 barrels, and heating oil sells for $40per 1,000 barrels. It takes 1 hour to process 1,000 barrels ofaviation fuel in the catalytic cracker, and these 1,000 barrelscan be sold for $130. It takes 45 minutes to process 1,000barrels of heating oil in the cracker, and these 1,000 barrelscan be sold for $90. Each day, at most 20,000 barrels of oilcan be purchased, and 8 hours of cracker time are available.Formulate an LP to maximize Sunco’s profits.2. A canning company produces two sizes of cans—regular and large. The cans are produced in 10,000-can lots. The cans are processed through a stamping operation and a coating operation. The company has 30 days available for both stamping and coating. A lot of regular-size cans require 2 days to stamp and 4 days to coat, whereas a lot of large cans requires 4 days to stamp and 2 days to coat. A lot of regular-size cans earn $800 profit, and a lot of large-size cans earn $900 profit. In order to fulfill its obligations under a shipping contract, the company must produce at least nine lots. The company wants to determine the number of lots to produce of each size can (and) in order to maximize profit. 8.

In a particular production process, three raw materials are blended (mixed together) to produce two products: a fuel additive and a solvent base. Each ton of fuel additive is a mixture of 2/5 ton of material 1 and 3/5 of material 3. A ton of solvent base is a mixture of 1/2 ton of material 1, 1/5 ton of material 2, and 3/10 ton of material 3. After deducting relevant costs, the profit contribution is $40 for every ton of fuel additive produced and $30 for every ton of solvent base produced.RMC’s production is constrained by a limited availability of the three raw materials. For the current production period, RMC has available the following quantities of each raw material:Raw Material Amount Available for ProductionMaterial 1 20 tonsMaterial 2 5 tonsMaterial 3 21 tonsAssuming that RMC is interested in maximizing the total profit contribution, answer the following:i.
