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

Answer:

(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.
