# A bookstore marks up the price of a book by 25% of the cost from the publisher. Therefore, thebookstore's price to the student, P (x) (in \$) after a 5.3% sales tax, is given by P (x) = 1.053 (x+0.25x),where x is the cost from the publisher. Evaluate P (60) and interpret the meaning in context of thisproblem. (Round to the nearest cent.)P (60) = 78.98When the bookstore spends \$60 on a textbook, the student pays \$78.98P (60) = 78.98When the bookstore pays \$78.98 on a textbook, the student pays \$60P (60) = 47.39When the bookstore pays \$47.39 on a textbook, the student pays \$60P (60) = \$47.39The sales tax on a \$60 textbook is \$47.39P (60) = 78.98The sales tax on a \$60 textbook is \$78.98P (60) = 47.39When the bookstore pays \$60 on a textbook, the student pays \$47.39

(A)

P (60) = 78.98 When the bookstore spends \$60 on a textbook, the student pays \$78.98

Step-by-step explanation:

Given:

P (x) = 1.053 (x+0.25x)

P (60) = 1.053 (60+0.25*60)

=1.053 (60+15)

=1.053 (75)

P (60) = \$78.98

Since x is the cost from the publisher, when the bookstore spends \$60 on a textbook, the student pays \$78.98.

The correct option is A.
