Thank you for the opportunity to help you with your question!

The total number of books sold to date= Whole fraction 1/1 =100%

Let the total number of books be 'X'

so the equation is

7.9% *X=35900

7.9/100 * X=35900

0.079X=35900

X=35900/0.079 = 454430.37

nearest whole number =454430 copies

Please let me know if you need any clarification. I'm always happy to answer your questions.
