Question

Store E offers a book that Karen wants for 20% off its regular price of $15. Store F sells the same book for $15, before a $3 mail-in rebate. Where should Karen purchase the book? Explain your reasoning. (Be sure to consider the cost of postage, as well as the time and effort required to mail in the rebate to request in your response.)

Answer 1

Karen should purchase her book from store E because 20% off would be $3 off making it $12 therfore store F would come to a total cost off $18 making it more expensive, meaning that Karen should buy her book from store E
