A customer buys a book with an original selling price of $45. The book is discounted 15%. What is the cost of the book in dollars, the customer pays for the discounted price of the book

Given:

Original selling price of a book = $45

Discount Rate = 15%

To find:

The cost of the book in dollars, the customer pays for the discounted price of the book.

Solution:

We know that,

Discounted price = Original price - Discount

                             = Original price - 15% of original price

Therefore, the discounted price of the book is $38.25. So, the cost of the book after discount is $38.25.
