Treasure Hunt – Part III
This has to be done sequentially. If you haven't seen Part I or II, do them first.

Back to Part II

You're traveling in Los Angeles. You happen to be on an avenue with the same name as the county in answer 14. You're hungry so you stop at an (15.) eatery that has been a Los Angeles landmark since 1931. Their menu brags that they have served more than how many pounds of lox? (16. Number.)

For the next part you'll need to do some math with at least 7 or 8 significant digits, so get some sort of digital electronic assistance.

Consider the following equation, in which answer 16 is simply the coefficient of x squared:

(answer 16)x² + 66,711,000 x – 6,025,593,321 = 0

This equation has two solutions. One is (17.) a latitude and the other is (18.) a longitude of a (19.) North American landmark. (It should be easy to figure out which is the latitude and which is the longitude, since if you reverse them, you'll end up in Antartica.)

That's it. The first to put the answers (numbered 1 through 19) in the comments is the winner. If Wanderer wins, I'll just buy him lunch. If anyone else wins, you can let me know what you'd like that costs $20 or less that can be arranged without much hassle over email / the web.

I sincerely hope this had some entertainment value for the puzzle geeks out there.

UPDATE: Ayelet is the winner! She get's a seat of honor at the Coffeehouse for life (ha! as if we'll be around that long), and if she ever tells me what she'd like as a prize, she'll get that too. She would also like our readers to visit her blog. - served up by Doctor Bean @ 12:07 PM
