Solve the linear programming problem. Maximize P = 30x + 40y Subject to attempted 2x+y ≤ 10 x+y ≤ 7 x + 2y ≤ 12 x, y ≥ 0 What is the maximum value of P? Select the correct choice below and fill in any answer boxes present in your choice. OA. P= (Type an integer or a fraction.) OB. There is no maximum value of P. What are the coordinates of the corner point where the maximum value of P occurs? Select the correct choice below and fill in any answer boxes present in your choice. OA. The coordinates are (Type an ordered pair.) OB. There is no maximum value of P.
