99 ! do not copy from other ! 99 !
tess and dan have $24.00 each to spend at a book fair, where all students receive a 15% discount. they both want to purchase a copy of the same book, which normally sells for $24.50 plus 10% sales tax. to check if she has enough to purchase the book, tess takes 15% of $24.50 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. dan takes 85% of the normal purchase price and then computes 110% of the reduced price. is tess correct? is dan correct? do they have enough money to purchase the book? explain your answer using complete sentences, and show your work.
