13. More on the time value of money The time value of money concept can be applied in various situations and is a fundamental concept underlying other financial concepts. Consider the following example of the application of this concept Megan is a divorce attorney who practices law in Dallas. She wants to join the American Divorce Lawyers Association (ADLA), a professional organization for divorce attorneys. The membership dues for the ADLA are $750 per year and must be paid at the beginning of each year. For instance, membership dues for the first year are paid today, and dues for the second year are payable one year from today. However, the ADLA also has an option for members to buy a lifetime membership today for $7,000 and never have to pay annual membership dues. Obviously, the lifetime membership isn't a good deal if you only remain a member for a couple of years, but if you remain a member for 40 years, it's a great deal. Suppose that the appropriate annual interest rate is 8.9%. What is the minimum number of years that Megan must remain a member of the ADLA so that the lifetime membership is cheaper (on a present value basis) than paying $750 in annual membership dues? (Note: Round your answer up to the nearest year) 13 years 17 years 18 years 20 years In 1626, Dutchman Peter Minult purchased Manhattan Island from a local Native American tribe. Historians estimate that the price he paid for the Island was about 124 worth of goods, including beads, trinkets, cloth, kettles, and axe heads. Many people find it laughable that Manhattan Island would be sold for $24, but you need to consider the future value (FV) of that price in more current times. If the $24 purchase pri could have been invested at a 5.50% annual interest rate, what is its value as of 2017 (391 years later)? $25,196,506,673.64 $29,643,054,910.16 $34,089,513,146.66 $39,128,832,481.41
