a)The basic variables and their values at the optimal point Z* are:.

b)In which range of the objective function coefficient belonging to x1 (c1 = 30), the optimal solution remains unchanged?

c)In which range of the right hand side of 2x1 + 3x2 120 (b2 = 120), the current basis (basic solution) remains unchanged?
