Hasan plans to choose a book from a section of the store where everything is 25% 25 % off. He writes the expression d?0.25d d - 0 . 25 d to find the sale price of the book if the original price is d d dollars. Bella correctly writes another expression, 0.75d 0 . 75 d , that will also find the sale price of the book if the original price is d dollars. Use the drop-down menus to explain what each part of Hasan's and Bella's expressions mean.

Hasan's expression 0.25d will find the amount of the discount in $$ for a 25% discount. By writing d-0.25d he will also find the sale price by subtracting the original by the discount in $$.

Bella's expression 0.75d finds the sale price for a 25% discount. If you receive 25% off then you pay 75%. Bella also wrote d-0.75d which gives the amount in dollars of the discount. By subtracting the sale price from the original, we find the deduction the sale gives.
