Ellen wants to purchase a book that 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 totle amount Ellen will pay for the the book ?

If the discount is 15%....then the cost of the book without the tax  must be 85% of what it normally cost


Also...if the tax is 6%, then she must multiply the discounted price by 1.06


So....the total cost of the book is  18 ( .85) (1.06)  ≈ $16.22
