I've Sold 4,714 Books on Kindle and 1,711 Copies on Paperback

I've sold about 3,000 copies on Kindle and 1,711 copies on paperback. The vast majority of money that I've made has been through the print copy because that one I make more on. But it was a little hard for me to see. I sold a thousand books. And what I only made $1,000 from those Kindle's,. I think that I could have maybe sold it for $3.99 and had very similar results. What do you think?
