Answer:
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
