linear programming Max 5A+5B

New to the forum, just wanted to see if someone can check my answer to the following...solve the following using graphical solution procedure:
Max. 5A+5B
s.t.
1A<=100
1B<=80
2A+4B<=400
A,B>=0

after using the graphical solution procedure to find the optimal solution for the equations....I arrived at point C with coordinates of 200,0 which, when plugged into the maximizing equation gives 1000.
Am I even close?

A=200, B=0, is not feasible (that is it does not satisfy the constraints)

The vertices of the feasible region are (0,0), (100,0), (0,80) (40,80) and (100,50). The optimum occurs at one of these.
