A bookstore marks up the price of a book by 40 % of the cost from the publisher. Therefore, the bookstore’s price to the student, P x in $ after a 7.5 % sales tax, is given by P x = 1.075 x + 0.40 x , where x is the cost of the book from the publisher. Evaluate P 60 and interpret the meaning in the context of this problem.
