Hasan plans to choose a book from a section of the store where everything is 25%25% off. he writes the expression d−0.25dd-0.25d to find the sale price of the book if the original price is dd dollars. bella correctly writes another expression, 0.75d0.75d, that will also find the sale price of the book if the original price is dd dollars. use the drop-down menus to explain what each part of hasan's and bella's expressions mean.

The solution would be like this for this specific problem:

Given:
25% discount

Hasan: d - 0.25d
Bella: 0.75d

d = original price.
0.25d = discount.
0.75d = discounted price.

 

Let’s say the price of the book is $1,000.

0.25d = 0.25(1000) = 250
0.75d = 0.75(1000) = 750

d - 0.25d = 1000 - 250 = 750

0.75d = 0.75(1000) = 750

Here's the answer ;)
