An objective function and a system of linear inequalities representing constraints are given. Graph the system of inequalities representing the constraints. Find the value of the objective function at each corner of the graphed region. Use these values to determine the maximum value of the objective function and the values of x and y for which the maximum occurs.Objective Function z = 7x + 6yConstraints x ? 0 y ? 0 3x + y ? 21 x + y ? 10 x + 2y ? 12
A. Maximum 68; at (8, 2) B. Maximum 66; at (6, 4) C. Maximum 65.5; at (5.5, 4.5) D. Maximum 60; at (6, 3)
