One of Jessuina’s New Year’s resolutions was to exercise more, so she bought an annual
membership to the gym that allows unlimited visits. Unfortunately, the gym is so
crowded and noisy that Jessuina leaves every day with a headache, without working out
at all. According to marginal analysis, Jessuina should:
A) continue using the gym for the year, since she has already paid for the membership.
B) join another gym only if a membership is cheaper at the new gym.
C) join another gym only if she can get a refund on her current membership.
D) stop using the gym.
