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.

First of all we need to calculate 25% of 26.50 and subtract it from the given amount.

Therefore the price will then be: 

(26.50 - 6.625). 

After calculating the price is now $18.34. Now we have to calculate the given tax (10%),

(10% × 18.34), = 1.834. 

Our next step is to add this amount to the discounted price: 

(18.34+1.834) = 20.12.

The final price of the book is $20.12 and Maria can get it and still save a little money. 

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
