Please note that this book is the Solution Manual for Hoy, et al's "Mathematics for Economics" and is *NOT* the solution manual for Pemberton's "Mathematics for Economists." Amazon's listing of these two together in their respective "Better Together" sections made me think that these books went together, at least initially.

Note the difference here: "Economics" vs. "Economists" in the titles of the books. Don't buy a solution manual for a book you don't have!
