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.
- "d" represents the original price of the game in dollars.
- "0.75d" represents the price of the game after the 75% discount is applied. This is found by subtracting 75% of the original price from the original price.
- "0.25d" represents the price of the game after the 75% discount is applied. This is found by multiplying the original price by 25% (which is equivalent to subtracting 75%).
d: The original price of the game in dollars.
0.75d: The amount by which the original price is reduced to find the sale price.
d - 0.75d: The sale price of the game, which is found by subtracting the amount of the discount from the original price.
0.25d: The amount of the discount that is applied to the original price of the game.
0.25*d: The sale price of the game, which is found by multiplying the discount by the original price and subtracting it from the original price.
d - 0.75d: This expression represents the original price (d dollars) minus 75% of the original price, which gives the sale price of the game. The expression can be simplified as 0.25d, which means that 25% of the original price gives the same sale price.
0.25d: This expression represents 25% of the original price (d dollars) and gives the sale price of the game. It is equivalent to the simplified version of the first expression, d - 0.75d.
