Maria and Edwin have $23.00 each to spend at a book fair, where all students receive a 25% discount. They both want to purchase a copy of the same book, which normally sells for $26.50 plus 10% sales tax. To check if she has enough to purchase the book, Maria takes 25% of $26.50 and subtracts that amount from the normal price. She takes 10% of the discounted selling price and adds it back to find the purchase amount. Edwin takes 75% of the normal purchase price and then computes 110% of the reduced price. Is Maria correct? Is Edwin correct? Do they have enough money to purchase the book? Expla

Best ResponseYou've already chosen the best response.1They both did the same thing in different forms. Maria: 25% of $26.50 = 0.25 * 26.5 = 6.625 26.5  6.625 = 19.875 10% * 19.875 = 1.9875 19.875 + 1.9875 = 21.8625 Rounds off to $21.86 Edwin: 75% of $26.50 = 0.75 * 26.5 = 19.875 Notice that Edwin found the discounter price with a single multiplication. 110% of 19.875 = 1.1 * 19.875 = 21.8625 Rounds off to $21.86 Here, Edwin use a multiplication to add the 10% tax The final prices are the same.
