B. can't possibly be the correct answer.  If it is, I could put a billion wood nails in a 1 lb bag, because 10^9/10 > 1.  Check your work, and certainly check the work of anyone who just gives you an answer without showing you how to get it!

whpalmer4 · Answer

Write an equation for the weight of $x$ penny nails and $y$ wood nails.  Set it to be less than 1 pound.

You'll then have to rearrange it a bit to match one of the answer choices.  It ought to be easy enough to rule out 2 of them if you think for a second.
