Answer:
The number of copies sold is statistically difficult to determine.
Explanation:
The determination of the number of books sold by a particular author is a <em>difficult task</em> going by the fact that, most of the sale are made online and at various stores. <em>Most of the customers that bought the books hardly leave feedback which would have aided in compiling the total number.</em>
Also, <em>some are sold as hard copies at various stores</em> available within the author's country of residence and outside of it.
In summary, while looking at the Amazon website, I am optimistic that the author, Artwoodwrite was able to sell a substantial amount of the book Brain friction (Wondering of the mind).
