Problem 7. range of feasibility) (1 point) Solve the linear program below using graphical methods (either the extreme point or iso-profit line methods). When entering your answers, specify the optimal solution as a point", i.e. enter coordinates X and Y as (X, Y). When entering a range (i.e. range of optimality 1. Use square brackets when the endpoint is included (all values except infinity) 2. Use parenthesis when the endpoint is not included. 3. Use -inf and inf to represent values of minus infinity and infinity respectively. For example, if the lower endpoint is 5 and the upper endpoint is 7.25, you would enter [5.7.25). If the lower endpoint is minus infinity and the upper endpoint is 1.65. you would enter (-inf, 1.65]. If the linear program cannot be solved, specify one of the following for the optimal value and specify O for all other answers: 1 - Solution is suboptimal 2- Empty feasible region 3 - Unbounded feasible region 4 - All other reasons Enter all values to two decimal places min 22.99Yi +4.717, s.t. 9.48Y+ 20.417; = 26 Y; Y >=0 Optimal value: Optimal solution: Range of optimality for Y Shadow price for constraint 2 Range of feasibility for constraint 2
