A. 90 lbs
And here's how I figured it out.
I divided 5 lbs of mass into 200 lbs of force = 40
And then I multiplied 2.25 x 40 = 90

A: 90 lbs, since the ratio of lb force to lb mass is implied to be a constant at 40 lbF/1 lbm (200 / 5). This problem is referring obviously to a situation in a gravitational field that would be 40 X as strong as that of the earth.

5/200:2.25/X
2.25 x 200 /5= 90lbs
