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.
For the expression d - 0.75d:
- "d" represents the original price of the game.
- "0.75d" represents the amount of the original price that is being subtracted, which is the 75% discount.
For the expression 0.25d:
- "0.25d" represents the amount of the original price that is being paid, which is the remaining 25% after the discount.
For the expression d - 0.75d:
- d represents the original price of the game in dollars.
- 0.75d represents the amount of the discount or the 75% off of the original price.
For the expression 0.25d:
- d represents the original price of the game in dollars.
- 0.25d represents the sale price of the game after applying the 75% discount or the amount saved.
For the expression d−0.75d:
- First, we have "d" which represents the original price of the game.
- Then, we have "-0.75d" which represents the amount being deducted from the original price to get the sale price.
For the expression 0.25d:
- First, we have "0.25" which represents the 75% discount on the game.
- Then, we have "d" which represents the original price of the game.
So, both expressions are used to calculate the sale price of the game by deducting the discount from the original price. The expressions just represent it differently.
