A store owner paid 15 dollars for a book. She marked up the price of the book by 40 percent to determine its selling price.
PART A - What is the selling price of the book? PART B - A customer buys a different book that has an original selling price of $38. The book is discounted by 25%. The customer must pay a 6% sales tax on the discounted price of the book. What is the total amount the customer pays for the discounted book?
part a: 21 dollars because you multiply .40 with 5 and get 6. you add the 6 to the 15 and get 21. part b: 30.21 because you multiply 38 by .25 and get the answer for that and then subtract that number from 38. then you multiply 0.06 by 38 and when u get that number, add that to the discounted price.
