Ellen wants to purchase a book that is regularly priced at $18. The book is discounted 15%. She also needs to pay a 6% sales tax on the discounted price.
What is the total amount Ellen will pay for the book?
the book costs 18*0.85 on sale, or 18*17/20 or 9*17/10, so it costs 15.30 dollars. now you add a 6% sales tax to get 16.22 dollars.
HOPE THIS HELPED!
