Hasan plans to choose a book from a section of the store where everything is 25Y% off. He writes the expression d- 0.25d to find the sale price of the book if the original
price is d dollars.
Bella correctly writes another expression, 0.75d, that will also find the sale price of the
book if the original price is d dollars.

expressions mean.
