Question

Hasan plans to choose a book from a section of the store where everything is 25% 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.
Use the drop-down menus to explain what each part of Hasan's and Bella's
expressions mean.

Answer 1

750

Explanation:

Given:

discount of 25%

Hasan's equation: d - 0.25d

Bella's equation: 0.75d

d represents the original price.

0.25d represents the discount.

0.75d represents the discounted price.

Example: 1,000 is the price. d = 1,000

0.25d = 0.25(1000) = 250 this is the discount

0.75d = 0.75(1000) = 750 this is the discounted price

Hassan: d - 0.25d = 1000 - 250 = 750

Bella: 0.75d = 0.75(1000) = 750
