Is the solution degenerate? $(10$ points$)$b$.$ Is the solution unique? $(10$ points$)$c$.$ Explain the signs of the reduced costs for each of the decision variables. That is$,$considering the optimal value of each decision variable, why does the sign of itsassociated reduced cost make economic sense? $(20$ points$)$d$.$ Suppose the cost per pound for Feed $3$ increased by $$3.$ Would the optimal solutionchange? Would the optimal objective function value change? $(20$ points$)$e$.$ If the company could reduce any of the nutrient requirements, which one should itchoose and why? $(20$ points$)$f$.$ If the company could increase any of the nutrient requirements, which one should it choose and why? $(20$ points$)$
