12 POINTS TO THE BRAINLIEST ANSWER!!!! PLEASE HELP!! 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. PLEASE ANSWER ALL QUESTIONS

Answer:

yes Dan and Tess have enough money because the price is 22.9075 after discount

Step-by-step explanation:

the  original price of the book=24.50

the price of the book with taxes : 24.5+(24.5*10 %)=26.95 Dollars

the price for the students is :  24.50-(24.5*15%)=20.825

the price to students +tax= 20.825+(20.825*10%)= 22.9075

See what Tess did:

she took 15 % from original price :24.50-(24.5*15%)=20.825

she took 10 % of discounted price :20.825.50*10%= 1.04125

adds it back to find the purchase amount:1.04125+20.825=21.86625

what Dan did:

Dan takes 85% of the normal purchase price: 24.50*85%= 20.825

then compute 110% to the discounted price: 20.825*110%=22.9075

Dan is right, he will pay 22.9075 which is actually the price that the student pay for the book after the discount. what Tess is that she calculated the tax before discount, she has to calculate the tax after discount.
