Hello! In this question, we are asked to find the original price of each book with the information given to us in our question.
__________________________________________________________
Step-by-step explanation:
Based on the information from the question, we know that:
- Mr. Olin purchased a total of 6 books
- Each book had a $3 discount
- After the discount was applied to each book, the total cost was $18 before tax.
With this information, we will be able to answer the question given.

Solve:
Since we know that $18 was the total price after the $3 discount was applied to each book, we can use this as a reference to our pre-discount total price.
To find the price of the books before the discount, we will multiply 6 by $3 to see how much money Mr. Olin saved with the discounts.

We now know that Mr. Olin saved $18 with the discounts. With this knowledge, we can add how much he saved in discounts to the total cost after discounts ($18) in order to find the total cost before the discounts were applied to each book.

We now know the total cost of the books before the discounts, which is $36. We can now divide the total cost by the number of books Mr. Olin purchased, which was 6 books, in order to find the original price of each book.

The original price of each book is $6.
