Question

Lloyd is a divorce attorney who practices law in Florida. He 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 $8,000 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 7.1%. what is the minimum number of years that Lloyd 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.) O 16 years O 22 years O 18 years O 14 years In 1626, Dutchman Peter Minuit purchased Manhattan Island from a local Native American tribe. Historians estimate that the price he paid for the island was about $24 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 price could have been invested at a 4% annual interest rate, what is its value as of 2012 (386 years later)? O $119,029,371.99 O $76,647,701.66 O $103,699,831.66 O $90,173,766.66

Explanation / Answer

Solution 1:

Let at n years of membership, life time membership and yearly membership are equivalent.

Therefore

Present value of yearly membership fee at n year = $8,000

$750 * Cumulative PV factor at 7.1% for for n periods = $8,000

Cumulative PV factor at 7.1% for for n periods = 10.666666

The PV Factor falls between 17 years and 18 years

Therefore Llyod must remain a member for 18 years of ADLA so that life membership fee is cheaper.

Solution 2:

Purchase price of manhattan islian in 1626 = $24

Rate of interest = 4%

Period (n) = 386 years

Value of manhattan island in 2012 after 386 year = P * (1+i)^n

= $24 * (1.04)^386

= $24 * 3757240.2776

=$90,173,766.66

Hence last option is correct.
