Answer: The maximum value of C is 15 Step-by-step explanation: we have -----> constraint A -----> constraint B -----> constraint C -----> constraint D using a graphing tool The solution area of the constraints in the attached figure we have the vertices (0,0),(0,9),(2,6),(5,0) Substitute the value of x and the value of y in the objective function (0,0) -----> (0,9) -----> (2,6) -----> (5,0) -----> therefore The maximum value of C is 15
