For the following questions, consider the following optimization problem: The Razor Me Club, Ltd., prepares and packages three razor packs for various club members as follows: Razor Pack Blade Refills Shave Gels Labor Units Profit /pack Weekender 2 1 2. $3.25 Traveler 3 2 2 $4.50 Expedition 6 3 1 $5.25 The company has a total of 2,800 blade refills, 1,500 shave gels, and 1,000 labor units available for packaging, and it believes that all razor packs can be sold (based on previous demand). The estimated profit for each razor pack is shown in the table above. To maximize profit, answer the questions below regarding the proper formulation of this optimization problem based on the LP algebra you would use to solve this in Excel using solver. What are the appropriate decision variables (the Xs)? Select one: O a. X1: Number of Blade Refills, X2: Number of Shave Gels, X3, Number of Labor Units O b. X1: Profit of Blade Refills, X2: Profit of Shave Gels, X3, Profit of Labor Units O c. X1: Number of Weekenders, X2: Number of Travelers, X3, Number of Expeditions O d. X1: Profit of Weekenders, X2: Profit of Travelers, X3, Profit of Expeditions O e. Both a. and b. What does the following formula represent: 2X1 + 3x2 + 6X3 = 0 Select one: O a. A constraint defined by the inventory of Blade Refills. O b. A constraint defined by the inventory of Shave Gels. O c. A constraint defined by the number of Labor Units. O d. A constraint defined by the inventory of Razor Packs. Oe. A non-negative constraint What is the appropriate objective function? Select one: a. MAX: 2 X1 + 1 X2 + 2 X3 Sales per Weekender O b. MAX: 3 X1 + 2 x2 + 2 X3 Sales per Traveler O c. MAX:3.25 X1 + 4.50 X2 +5.25 X3 Profit per pack O d. MIN: [2*3*6] X1 + [1* 2 * 3] X2 + [2* 2* 1] X3 Profit per pack O e. MAX: [2 * 3 * 6] X1 + [1* 2 * 3] X2 + [2* 2* 1] X3 Sales Which of the following is the proper formula representing the constraint for Labor Units Select one: O a. 2X1 + 3X2 + 6X3 = 0 O e. X1, X2, X3 >= 1500
