**Steve**, Friday, August 15, 2014 at 10:34amset it up as a units conversion problem.

b books = d dollars, so

b bk/d dol = 1

d dol/b bk = 1

That is, books go at the rate of b/d books/dollar, or d/b $/bk

Now, you want to convert d books to dollars. You can always multiply by 1, so do it to cancel the units you don't want.

d books * d dol/b books = d^2/b dol
