I thought you were just giving a made up example to make a point. I do think you are pricing your ebook too low. As long as your paperback is selling decently at 15.00, I think that most people would consider 9.99 for the ebook more than fair. Using the math that you did, it would give you 6.64 instead of 6.28, while also giving the reader a substantial discount. If your ebook is only 5 dollars, you will lose money in comparison to your paperback. I used the number 9.99 because for a long time it seemed to be the "standard" price for an ebook. Lately the costs have been going up pretty rapidly. Pricing a product does take a lot of time and research. I haven't published a book before, but I have bought lots of ebooks. When I look at a book on Amazon, if the price of the ebook is at least 33% less than the price of a paperback or hardcover, I'll at least consider it. If there isn't a significant price advantage, I wouldn't ever purchase an ebook that is readily available on paper. I think that the best bet is to first decide how much money per book you want to have in your pocket once all is said and done. The amount of money you are comfortable receiving should guide your prices. Once you have a ballpark figure, you can tweak the price just a little to see if you can increase your volume.
