13 4 points Your manager approaches you and says that he made a mistake and there are only 900 products available for constraint 1, rather than 1000. He/she wants you to tell him/her if it is possible to make the change and still stay within the range of feasibility. O Yes, it is possible since constraint 1 can be reduced to 420. Yes, it is possible since constraint 1 can be reduced to 540. Yes, it is possible since constraint 1 can be reduced to 460. O No, it is not possible as it will fall outside the range of feasibility.O No, it is not possible as it will fall outside the range of feasibility. 14 4 points Your manager tells you that he wants to change the amount of product for constraint 3 from 800 to 850. He wants you to tell him by how much the objective function will be changed? O There will no be change as the shadow price for constraint 3 is 0. It is not possible to change constraint 3 as it will be outside the range of feasibility. There will be a change as the shadow price for constraint 3 is 1. O There will be a change as the shadow price for constraint 3 is 2.5
