Minx1+2x2 s.t. x1+x23002x1+x24002x1+5x2750x1,x20\begin{array} { l r } \operatorname { Min } & x _ { 1 } + 2 x _ { 2 } \\\text { s.t. } & x _ { 1 } + x _ { 2 } \geq 300 \\&2 x _ { 1 } + x _ { 2 } \geq 400 \\&2 x _ { 1 } + 5 x _ { 2 } \leq 750 \\&x _ { 1 } , x _ { 2 } \geq 0\end{array}
a.Keeping c2 fixed at 2, over what range can c1 vary before there is a change in the optimal solution point?
b.Keeping c1 fixed at 1, over what range can c2 vary before there is a change in the optimal solution point?
c.If the objective function becomes Min 1.5x1 + 2x2, what will be the optimal values of x1, x2, and the objective function?
