The author of a book on running receives a royalty of 75¢ per copy sold. If the royalty rate is 12% of the single copy price, how much money per copy does not go to the author?
To find out how much money per copy does not go to the author, we first need to determine the single copy price of the book.
Let's assume the single copy price of the book is "P".
Since the royalty rate is given as 12% of the single copy price, the author's royalty per copy is 0.12P.
However, we also know that the author receives a royalty of 75¢ per copy sold.
Therefore, we can set up the following equation:
0.12P = 0.75
To solve for P, we can divide both sides of the equation by 0.12:
P = 0.75 ÷ 0.12
P = 6.25
So, the single copy price of the book is $6.25.
Now, let's calculate the amount of money per copy that does not go to the author:
Amount not going to the author = Single copy price - Author's royalty per copy
Amount not going to the author = $6.25 - $0.75
Amount not going to the author = $5.50
Therefore, $5.50 per copy does not go to the author.
.12 * 75 = 9 cents to author
75 - 9 = 66 cents to publisher or whatever
