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

Answer: Hassan's expression:

d = original price

0.25d = amount of discount

d-0.75d= sale price of the book

Bella's expression

0.75d = sale price of a book

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

d = original price in dollars

25% off = 0.25 in decimal form ( 25/ 100 = 0.25)

Hasan's expression:

d−0.25d

In this expression 0.25d is the amount of discount , and d is the original price.

For example :

If a book costs $100 (original price) :

sale  price =100 - (0.25 x 100)

sale price=100- 25

sale price=75

Bella's expression:

0.75d

in this expression 0.75d is the sale price ( d is the original price and since the percent discount is 0.25 it can be expressed as a 0.75 of the original price since 100-25=0.75)
