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.

Answer 1

Answer:

Step-by-step explanation:

Tess is wrong while Dan is correct. This is because tax is calculated after discount.

Finding the correct amount they are supposed to pay:

Price after discount = 85/100 x 24.5 = 20.825

Price after tax = 110/100 x 20.825 = 22.90

Since they have $24 each, it means they can purchase the book
