Question

Maria and Edwin have $23.00 each to spend at a book fair, where all students receive a 25% discount. They both want to purchase a copy of the same book, which normally sells for $26.50 plus 10% sales tax. To check if she has enough to purchase the book, Maria takes 25% of $26.50 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. Edwin takes 75% of the normal purchase price and then computes 110% of the reduced price. Is Maria correct? Is Edwin correct? Do they have enough money to purchase the book? Explain your answer using complete sentences and show your work

Answer 1

Alright, so what do you think?

Answer 2

so im assuming the tax is the last thing that goes, so first yo want to find the discount amount then 10% tax that

Answer 3

So Maria takes 25% off and subtracts it (finding the discount price) and then Maria finds the 10% discount price and adds it, so she is correct.
Now edwin takes 75%, same as reducing 25% and then takes 110% of that, which is just adding 10% to 100% so they both are correct

Answer 4

Can you find if they have enough money to purchase the book?
