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 $ 87.00 comma how much did the bookstore pay for this​ book?

Answer 1

Answer:the amount that the bookstore pay the publisher for the book is $64.4

Explanation:

Let x represent the amount that the bookstore pay the publisher for the book.

The college bookstore marks up the price that it pays the publisher for a book by 35%. This means that the value of the mark up would be

35/100 × x = 0.35 × x = 0.35x

Therefore, the amount that the bookstore is selling the book would be

x + 0.35x = 1.35x

If the selling price of a book is $ 87.00, then it means that

1.35x = 87

x = 87/1.35 = 64.4
