Question 19 3 Points An LP may have feasible solution even though an artificial appears at a positive level in the optimal iteration True False Question 20 3 Points The Huge State U Bookstore buys textbooks from two suppliers Gigantic Textbooks Inc. and HeftyBooks & Co. Gigantic Textbooks Inc. offers packages of 5 physics textbooks and relativity textbooks at Php 5000 per package, and Hefty Books & Co. offers packages of 5 physics textbooks and 10 relativity textbooks at PhP 4150 per package. The bookstore needs to buy at least 2.500 physics textbooks and at least 3,500 relativity textbooks. Further the faculty stipulate that at most 75% of the total number at packages must be from Ggantic Textbooks inc. How many packages should the bookstore order from each suppler to satisty the above requirements at the least possible cost? What are the decision variables? ** Gigantic Textbooks Inc. y - HeftyBooks & Co. x-the number of packages of physies textbooks, ythe number of packages of relativity textbooks - total cost of the packages from Gigantic Textbooks Inc. y u total cost of the packages from HeftyBooks & Co x the number of packages from Gigantic Textbooks Inc.y - the number of packages from Hetty Books & Co.

A True B False Question 18 3 Points If a problem has one 2 constraint and one constraint and the two do not intersect in the quadrant of the graph where both variables are positive: A The solution is unbounded. B One of the constraints is redundant. The problem is infeasible. D None of the above ti 2 Pointe Question 16 3 Points If for a given solution, a slack variable is equal to zero, then: A All of the above B the solution is optimal The entire amount of the resource identified with the constraint in which the slack varlable appears has been used up by the products in the solution mix The solution is not feasible
