if x = original price of book than

 

x+.15x = price of book after first markup = 1.15x and

 

1.15x+.15(1.15x) = price of book after 2nd markup or 1.3225x is the price of the book after both markups

 

so whatever the price of the book multiply it by 1.3225 and that will get you the price up the book marked up twice by 15%
