A bookstore marks up the price of a book by 25% of the cost from the publisher. Therefore, the

bookstore'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 this

problem. (Round to the nearest cent.)

P (60) = 78.98

When the bookstore spends $60 on a textbook, the student pays $78.98

P (60) = 78.98

When the bookstore pays $78.98 on a textbook, the student pays $60

P (60) = 47.39

When the bookstore pays $47.39 on a textbook, the student pays $60

P (60) = $47.39

The sales tax on a $60 textbook is $47.39

P (60) = 78.98

The sales tax on a $60 textbook is $78.98

P (60) = 47.39

When the bookstore pays $60 on a textbook, the student pays $47.39
