1 points QUESTION 21 Taco Loco is considering a new addition to their menu. They have test marketed a number of possibilities and narrowed them down to three new products, x, Y, and Z. Each of these products is made from a different combination of beef, beans, and cheese, and each product has a price point. Taco Loco feels they can sell an x for $17, a Y for $13, and a Z for $14. The company's management science consultant formulates the following linear programming model for company management. Taco Loco is unsure whether the amount of beef that their computer thinks is in inventory is correct. What is the range in values for beef inventory that would not affect the optimal product mix? 26 to 38.22 pounds 27.55 to 28.45 pounds 17.78 to 30 pounds
