Yes, Maria and Edwin have enough money to purchase the book. To calculate the purchase amount, we first need to calculate the discounted selling price. Since they both receive a 25% discount, we can multiply the original price of the book by 0.75 to find the discounted selling price. Then, we can take 10% of the discounted selling price and add it back to find the purchase amount. Finally, we can compare the purchase amount to the amount of money Maria and Edwin have to determine if they have enough money to purchase the book.
Purchase Amount = (Original Price x 0.75) + (Original Price x 0.75 x 0.10)
Purchase Amount = (Original Price x 0.825)
Since Maria and Edwin have $23.00 each, they have a total of $46.00. Since the purchase amount is less than $46.00, they have enough money to purchase the book.
