Answer:

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

He writes the expression [tex]d-0.75d[/tex]

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 [tex]d-0.75d[/tex]

For example:

Let the price of an item be = $100

So, price will be = [tex]100-0.75(100)=25[/tex] dollars

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

Rena correctly writes another expression, [tex]0.25d[/tex]

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 = [tex]0.25\times100=25[/tex] dollars
