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
Viefleur [7K]

Answer:

Ellen will pay $16.22 for the book.

Step-by-step explanation:

Part 1:

We know that the book Ellen wants to buy has a normal price of $18. However, there is a 15% discount. So, let's calculate 15% of $18.

18 x 0.15 = $2.70

This lets us know that there is a $2.70 discount.

Now, let's subtract the discount from the regular price.

18 - 2.70 = $15.30

So, now we know the discounted price is $15.30

Part 2:

We also know that Ellen has to pay 6% sales tax. The discounted price is 100% of the price, plus 6% is 106%. Let's calculate the tax to figure out the total amount.

15.30 x 1.06 = $16.22 when rounded to the nearest cent.

Therefore, Ellen will pay the total amount of $16.22.
