I have a website: http://www.thepotatosoup.com It earns 85 cents a day about (from adsense and infolinks), so how much should I sell it for?
I think you shouldn't sell it yet! just 85 cents per days is not much, you should working on get more traffic and can get more money per day then you will sell it for a great price!
You are trying to rank for potato soup > Build the site > make backlinks > when you will be ranking potato soup 1st place sell it for 2000$ on flippa or keep the passive income.
