Provide an appropriate response.Use the big M method to find the optimal solution to the problem.Maximize P = 6x1 + 2x2subject to x1 + 2x2 ? 20 2x1 + x2 ? 16 x1 + x2 ? 9 x1, x2 ? 0
A. max P = 46 at x1 = 7 , x2 = 2 B. max P = 46 at x1 , x2 = 2 C. max P = - 46 at x1 = 2 , x2 = 7 D. max P = 46 at x1 = 2 , x2 = 7
