**Question**

Question;Questions 2-77 through 2-80 refer to the following;The owner;of Crackers, Inc. produces both Deluxe (D);and Classic (C) crackers. She only has 4,800 ounces of sugar, 9,600;ounces of flour, and 2,000 ounces of salt for her next production run. A box of;Deluxe crackers requires 2 ounces of sugar, 6 ounces of flour, and 1 ounce of;salt to produce. A box of Classic;crackers requires 3 ounces of sugar, 8 ounces of flour, and 2 ounces of salt to;produce. Profits are 40 cents for a box;of Deluxe crackers and 50 cents for a box of Classic crackers.;2-77 What is the;objective function?;a. P = 0.5D + 0.4C.;b. P =0.2D + 0.3C.;c. P = 0.4D + 0.5C.;d. P = 0.1D + 0.2C.;e. P =0.6D + 0.8C.;2-78 What is the;sugar constraint?;a. 2D + 3C;? 4,800.;b. 6D + 8C? 4,800.;c. 1D + 2C? 4,800.;d. 3D + 2C? 4,800.;e. 4D + 5C? 4,800.;2-79 Which of the;following is not a feasible solution?;a. (D, C) = (0, 0).;b. (D, C) = (0, 1000).;c. (D, C) = (800, 600).;d. (D, C) = (1600, 0).;e. (D, C);= (0, 1,200).;2-80 What is the;daily profit when producing the optimal amounts?;a. $800.;b. $500.;c. $640.;d. $620.;e. $600.;Questions 2-81 through 2-84 refer to the following;The;operations manager of a mail order house purchases double (D) and twin (T) beds for;resale. Each double bed costs $500 and;requires 100 cubic feet of storage space.;Each twin bed costs $300 and requires 90 cubic feet of storage space. The manager has $75,000 to invest in beds;this week, and her warehouse has 18,000 cubic feet available for storage. Profit for each double bed is $300 and for;each twin bed is $150.;2-81 What is the;objective function?;a. P = 150D + 300T.;b. P = 500D + 300T.;c. P = 300D + 500T.;d. P = 300D + 150T.;e. P = 100D + 90T.;2-82 What is the;storage space constraint?;a. 100D + 90T? 18,000.;b. 100D + 90T? 18,000.;c. 300D + 90T? 18,000.;d. 500D + 100T? 18,000.;e. 100D + 90T? 18,000.;2-83 Which of the;following is not a feasible solution?;a. (D, T) = (0, 0).;b. (D, T);= (0, 250).;c. (D, T) = (150, 0).;d. (D, T) = (90, 100).;e. (D, T) = (0, 200).;2-84 What is the;weekly profit when ordering the optimal amounts?;a. $0.;b. $30,000.;c. $42,000.;d. $45,000.;e. $54,000.
