To find the values of each vertex in the objective function P=5x+6y and the maximum value, we need to find the coordinates of each vertex of the shaded area.

The three points given are:
Point A: (0, 8)
Point B: (5, 4)
Point C: (9, 0)

To find the coordinates of the vertices, we can look at the x and y coordinates separately.

For the x coordinates:
The x coordinate of the vertex at the left end of the shaded area is 0.
The x coordinate of the vertex at the right end of the shaded area is 9.

For the y coordinates:
The y coordinate of the vertex at the top end of the shaded area is 8.
The y coordinate of the vertex at the bottom end of the shaded area is 0.

So the vertices of the shaded area are:
Vertex A: (0, 8)
Vertex B: (9, 8)
Vertex C: (9, 0)
Vertex D: (0, 0)

Now we can substitute these coordinates into the objective function P=5x+6y to find the values of each vertex:

P(A) = 5(0) + 6(8) = 0 + 48 = 48
P(B) = 5(9) + 6(8) = 45 + 48 = 93
P(C) = 5(9) + 6(0) = 45 + 0 = 45
P(D) = 5(0) + 6(0) = 0 + 0 = 0

The maximum value is 93, which occurs at vertex B.
