Question: Visualization 3D

Hello,
I try to visualize this formula in a 3D graphic.
However, I get again and again this error message displayed and unfortunately knows no more solution.
I am a total beginner with Maple, I hope here can help me.

plot3d(100*(0,15+0,035*x)+100*(0,15+0,035*9), 100*(35*9))+0,05*(100-(100*(0,15+0,035*x)))*(0,15+9*y), x = 2 .. 9, y = 0, 1 .. 0, 45, axes = boxed);

Error, (in plot3d) unexpected options: [5*(100+(0, -1500, -3500*x))*(0, 15+9*y), x = 2 .. 9, y = 0, 1 .. 0, 45]
