Question

A college bookstore marks up the price that it pays the publisher for a book by 35%.  If the selling price of a book is $54.00, how much did the bookstore pay for this​ book?

Answer 1

Answer:

$40.

Step-by-step explanation:

Let x be the original price of book.

We have been given that the a college bookstore marks up the price that it pays the publisher for a book by 35%.

The selling price of a book at college bookstore would be x plus 35% of x.

$x+\frac{35}{100}x=x+0.35x=1.35x$

We are told that the selling price of a book is $54.00. We can represent this information in an equation as:

$1.35x=54.00$

$\frac{1.35x}{1.35}=\frac{54.00}{1.35}$

$x=40$

Therefore, the bookstore paid $40 for the book.

Answer 2

The answer is $18.90 because 35% of 54.00 is $18.90
