Vectors Problem: wheelchair on a ramp inclined at an angle of 20 degrees

[AWildZeebra]

Devon is holding his father's wheelchair on a ramp inclined at an angle of 20 degrees to the horizontal with a force of magnitude 2000 N parallel to the surface of the ramp. Determine the weight of Devon's father and his wheelchair and the component of the weight that is perpendicular to the surface of the ramp.

The answer in the back of the textbook is 59.7 kg; 549.5 N

I'm not sure what I'm doing wrong but I seem to be a factor of 10 off

Here's a picture of my work:

1) Don't use imgur. We officially hate all those ads.
2) Maybe the book meant 200N?
