Yeah jarchive is pretty sick. You can open up almost any past show, see how the game played out (also look at questions and answers). Then at the bottom there's a "see wagering suggestions for these scores" that gives similar links to the one I gave. There's actually a lot of special cases for final Jeopardy wagering. You'll notice on that link I gave, it said "four-fifths for first place" (which is a special case). Read those links if you want further explanation, as those links explain the logic behind the suggested bets in more detail.
Also, I wouldn't feel to bad about not knowing how to wager final jeopardy
It's fairly complicated, and only really necessary to learn if you're going to be on the show. Now if you had $20000 riding on knowing how to properly wager, I would make fun of you for not spending an hour or two learning correct wagering strategy.
