d-0.75d: Adam's expression for the sale price of the video game
0.25d: Rena's expression for the sale price of the video game
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.
Drag each description to explain each part of both expressions.
