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
<h2>See what Tess did:</h2>
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
<h2>what Dan did:</h2>
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.
