The bookstore pay $44.8 for the book.
Explanation:
It is given that, a college bookstore marks up the price that it pays the publisher by 25%.
We need to find out the price the bookstore pay for the book, if the selling price of a book is $56.
Let us take,
- The price of the book paid to the publisher be 'x'.
- We already know that the price of the book is $56.
To find the value of x :
⇒ x + 25% of x = 56
⇒ x + 0.25x = 56
Solving for x ,
⇒ 1.25x = 56
⇒ x= 56 / 1.25
⇒ x = $44.8
Therefore, the bookstore pay $44.8 for the book.
