Jia is trying to decide whether or not to attend her class this afternoon. She tells her friend that she will miss the class, because she thinks she will get zero benefit from attending it. Her friend points out that since she pays approximately $750 per paper, and this paper has a total of 48 hours of classes, then each class is worth $15.63. Therefore to miss one of her classes will make her a loss of $15.63. Jia has already paid her fees, and this payment is non-refundable. Based on Jia and her friends comments, which of the following is correct?
