Answer: The required selling price of the game is $27.5.
Step-by-step explanation: Given that Marc bought a new video game for $50. After beating the game he sold it for 45% less than the original price.
We are to find the selling price of the game.
Since the video game is sold at loss, so the selling price will be equal to the cost price minus the loss.
The loss in selling the video game is
![45\%*50\\\\\\=(45)/(100)*50\\\\\\=(9)/(20)*50\\\\=22.5.](https://img.qammunity.org/2020/formulas/mathematics/middle-school/xqhm7pwzozyvsgt206elfr0zb2jt7shivw.png)
Therefore, the selling price of the game is given by
![50-22.5=27.5.](https://img.qammunity.org/2020/formulas/mathematics/middle-school/59a4mzy9snz9bdeyqvdqhu2ccctopl77m5.png)
Thus, the required selling price of the game is $27.5.
