Question 2

Just before class, Jim tells Stuart, Stuart, you shouldn't skip class today because you have paid tuition to enroll in the class. Stuart ignores Jim's advice, and instead makes the decision of whether to attend based on the importance to his grade that he feels he'd be missing that day in class relative to his value of the extra time he could have to finish the video game he is playing. To an economist, Stuart is:
 a. using marginal analysis. b. ignoring the total value of attending class.
