How much does it cost to replace an old rented video game?

I've been looking for an old Xbox 360 game but can't find it anywhere to buy, so I rented it. Say I go back to the video store in a week and explain how I 'lost' the game, will I be charged the amount they bought the game for like 4 years ago?How much does it cost to replace an old rented video game?yea thats what happened to me but you can try to convince the guy that the game isnt worth the value and be like its so cheap but its not local so i should just pay the 5 bucks or so its worth it will work!
