Graphically solve the following problem: Maximize profit = 8X1 + 5X2 subject to X1 + X2 s 10 X1 s 6 X1, X2 2 0 (a) What is the optimal solution? Data x1 x2 Maximize 8 5 sign RHS Constraint 1 1 constraints 10 0 Constraint 10 10 10 10 10 Constraint 10 10 6 Results Variables 6 Objective (b) Change the right-hand side of constraint 1 to 11(instead of 10) and resolve the problem. How much did the profit increase as a result of this? Data x1 X2 Maximize 5 sign RHS Constraint 1 1 constraints 11 0 Constraint 11 11 11 11 6 0 Constraint 6 6 Results Variables 6 5 Objective 73 The profit increased by 5
