Question: The following tableau gives an optimal solution to a standard linear program: Maximize: Z=cx, Subject to Ax=b,x0 Assume that (x4,x5) were the initial basic variables.

The following tableau gives an optimal solution to a standard linear program: Maximize: Z=cx, Subject to Ax=b,x0 Assume that (x4,x5) were the initial basic variables. (a) How much can c3 be increased before the current basis is no longer optimal? Find an optimal solution when c3=6. (b) How much can c1 be varied so that the given basis (x1,x2) is still optimal? (c) How much can b2 (the original value) be varied before the given basis (x1,x2) is no longer feasible
