Adam's expressions

d-0.75d

"d" Means the original price of the video game in dollars minus the 75% discount on the original price of the video game (-0.75d). This results in what Adam must pay for the video game.

rena's expressions

0.25d

"0.25d" It means the price that must be paid for a video game, knowing that there is a discount of 75%. Therefore the expression of rena directly gives the dollar amount that must be paid for a video game.
