You would have to embed the fonts. This requires some technical know-how, and you must have permission to use the font -- some are free, but most are not. (Microsoft pays the owners to install fonts on your computer, for your use, but not for you to turn around and use them in a book. That requires a license, or it requires embedding a free font, most of which are inferior.)
Finally, you run the risk that Amazon may strip out the fonts, or that the reader doesn't have "Publisher Fonts" authorized so will not see your fonts, or that he will see them and be irritated and give you a one-star review.
Don't do it, Janet. Let the defaults rule.

$49 does not seem like a lot if it is a font that you definitely want for your book. I followed your link, and the page there says you can use that particular font "in print."
You are quite right--and $49 is outright cheap to license a font for redistribution/ePUB. We have clients that have paid hundreds of dollars for a single font (not even necessarily a font family, mind you) for a book. (We recently had a client that paid over $150--for a single font to use for a DROPCAP. One letter per chapter. Yowza! I tried, I did, to get her to look at alternatives that would be less financially painful, but that's NOT what she wanted--and so, we gave her what she wanted. And yes...the font looks stunning, one letter at a time. )
