To find out how much was the book profit in the entire month, subtract the number of copies at the start of the month from the number of copies at the end of the month, and the result multiply by $13.97 (each book profits)
so
[tex](1,364-885)(13.97)\\479(13.97)=\$6,691.63[/tex]
so
approximately $6,706
