Please show the steps clearly

Given the Excel Solver output: a) Give the mathematical model. Notel: The isn't any free variable (urs) in the primal model. Note: If a constraint is binding, then assign the sign of the constraint b) Give the dual of the LP that you find in part (a). Note3: Don't multiply a by -1 to change the sign of the constraint of the primal model before find c) Give the dual optimal solution (w* and y* values) based on the Excel Solve (Don't attempt to solve it!)
