Demarcus says that a store overcharged him on the price of video game he bought he thought that the price was marked one over four of the original price but it was really one over four off the original price he miss heard the observation if the original price of the game was $48 what is the difference between the price that the market the store charged him

If the original price of the game was $48, and Demarcus thought it was marked one over four of the original price, that means he expected to pay 1/4 * $48 = $12 for the game.

But in reality, the store was offering a discount of one over four off the original price, which means the price was reduced by 1/4 * $48 = $12.
So, the actual price charged by the store was $48 - $12 = $36.
The difference between the price Demarcus expected to pay and the price the store charged him is $12 - $36 = -$24.
