Based on the given assumptions and the data in Exhibit 1, the additional amount of life insurance coverage needed is closest to:
选项：
A. A$0.
B. A$331,267.
C. A$2,078,101.
解释：
B is correct.
The additional amount of life insurance coverage needed is calculated as the di₤erence between the family’s total financial needs and total capital available. Total financial needs are calculated as follows.
Capital needs are determined as the present value of an annuity due: growth rate = 3.5%, discount rate = 6.0%. Growth of payments is incorporated by adjusting the discount rate to account for the growth rate of earnings. As long as the discount rate is larger than the growth rate, the adjusted rate i can be calculated as follows: [(1 + Discount rate)/(1 + Growth rate)] – 1, or i = (1.06/1.035) – 1 = 2.42%.
题目中并没有说明Olivia 的Income是先付，为什么要用payment at beginning of the year? Income一般情况下应该是后付吧？
