Question

Adam plans to choose a video game from a section of the store where everything is 75% off. He writes the expression d−0.75d to find the sale price of the game if the original price is d dollars.

Rena correctly writes another expression, 0.25d, that will also find the sale price of the game if the original price is d dollars.

Use the drop-down menus to explain what each part of Adam's and Rena's expressions mean.

Answer 1

is 0.75d becase the missing numbers should be the same number

Answer 2

d is the marked price

0.75 is the 75% discount

0.75d is the change in price

d - 0.75d

Is cost - discount = paid

0.25 is the percentage of amount to be paid.

0.25d is the amount paid

d is the marked price
