In many cities, discount clubs are popular. For a fixed annual fee (paid in advance) one can purchase goods at 82% of their listed price (in other words, 18% off the list price); otherwise, one pays the list price. Suppose that the annual fee is $200 and the interest rate on your savings account is 5%. Finally, assume discount club's list prices are the same as any other store, and you plan to spend $3000 over the coming year at this store. (Hint: the interest represents an opportunity cost of purchasing a membership). The benefit of not buying a membership is dollars and the cost of not buying a membership is dollars.
