Question

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.

Answer 1

Both are correct.

Using Dan's method:
$24.50 x 0.85 = $20.825
$20.825 x 1.10 = $22.9075
$22.9075 < $24.00, therefore Tess and Dan have enough money.

You can think about how to write this in complete sentences.
