Allushta [10]

Answer:

<h2>  $24</h2>

Step-by-step explanation:

The question is not complete, here is the complete question

"<em>DeMarkus says that a store overcharged him on the price of the video game he bought. He thought that the price was marked 1/4 of the original price, but it was really 1/4 off the original price. He misread the advertisement. If the original price of the game was $48, what is the difference between the price that DeMarkus thought he should pay and the price that the store charged him?"</em>

<h2 /><h2>Solution</h2><h2>Take note of the words "of" and "off" </h2>

1/4 of $48= 0.25*48=$12

so he thought he should pay $12

1/4 off $48= $48-$12= $36

now the difference is

36-12= $24
