Solve the following model graphically, using an 8 by 8 grid. maximize subject to 7x1 + 3x2 (1) 8x1 + 2x2<32 (2) x1+ 5x2 < 25 (3) 10x1+ 2x2 < 39 (4)4x1 + 5x2 < 30

x1, x2 > 0 (b) Perform a sensitivity analysis for each of the objective function coefficients. (c) Perform a sensitivity analysis for the right-hand-side values for each of the non- binding constraints. (d). Perform a sensitivity analysis for the right-hand-side values for each of the two bind- in constraints. (e) For each of the two binding constraints, find the change to each variable as function of the right-hand side value, and from these relationships calculate the two shadow prices
