The production planner for a private label soft drink maker is planning the production of two soft drinks: root beer (R) and sassafras soda (S). There are at most 12 hours per day of production time and 1500 gallons per day of carbonated water available. A case of root beer requires 2 minutes of time and 5 gallons of water to produce, while a case of sassafras soda requires 3 minutes of time and 5 gallons of water. Profits for the root beer are $6.00 per case, and profits for the sassafras soda are $4.00 per case. What is the objective function? ( ) (A) P = 4R+6S. (B) P = 2R+3S. (C) P = 6R+4S. (D) P = 3R+2S. (E) P = 5R+5S. What is the time constraint? ( ) (A) 2R+3S 720. (B) 2R+5S 720. (C) 3R+2S 720. (D) 3R+5S 720. (E) 5R+5S 720. Which of the following is not a feasible solution? ( ) (A) (R,S) = (0,0). (B) (R,S) = (0,240). (C) (R,S) = (180,120). (D) (R,S) = (300,0). (E) (R,S) = (180,240)
