Mark Young has just won the state lottery, paying $50000 a year for 20 years.He is to receive this first payment a year form now. The state advertises this as the Million Dollar Lottery because $ 1000000= $50000 x 20. If the interest rate is 8 percent, what is the true value of the lottery?

马克赢得了一笔州彩票，金额为1000000美元，但要20年分期，每期5万美元，第一笔奖金一年后收到。

解答：

Million Dollar Lottery = 50000 x{1/0.08 – 1/[0.08(1.08)20])}

Million Dollar Lottery = 50000 x{1/0.08 – 1/[0.08(1.08)19])}

Trick 1: Delayed Annuity

Danielle Caravello will receive a four-year annuity of 500 per year, beginning at data 6.If the interest rate is 10 percent, what is the present value of her annuity?

0 1 2 3 4 5 6 7 8 9 10

500 500 500 500 500

Trick 2: Annuity in Advance 先付年金

In a previous example, mark Young received 50000 a year for 20 years.In that example, he was to receive the first payment a year from the winning data. Let us now assume that the first payment occurs immediately. The total number of payments remains 20.

接Mark Young例子，如果第一期奖金立即收到，而不是一年后才能收到，维持20期的奖金，那么又如何计算呢？

Trick 3： The Infrequent Annuity 不规则年金

Miss Ann Chen receive an annuity of 450, payable once every two years. The annuity stretches out over 20 years. The first payment occurs at date 2, that is, two years from today. The annual interest rate is 6 percent.

Ann Chen小计每次收到450，每两年一次，期限20年，第一次收到付款是在第二期，每年利息率是6%。

Trick 4: Equating Present Value of Two Annuities

Harold and Helen Nash are saving for the college education of their newborn daughter, Susan. The Nashes estimate that college expenses will run 30000 per year when their daughter reaches college in 18 years. The annual interest rate over the next few decades will be 14 percent. How much money must they deposit in the bank each year so that their daughter will be completely supported through four years of college.

Nash夫妇为刚出生的女儿存款。......
