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

Adam plans to choose a video game from a section of the store where everything is 75 % off .

He writes the expression

Where d is the original price is d dollars.

75% off on d is represented as 0.75d.

And 0.75d is subtracted from original price d to get the price after discount. Hence, the equation forms

For example:

Let the price of an item be = $100

So, price will be = dollars

---------------------------------------------------------------------------------------

Rena correctly writes another expression,

This means that 25% of d will be charged.

This is also correct.

Same example as above.

Let the price be = $100

Price will be = dollars
