问题如下：
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%.
老师我不太明白这个needs analysis method和human life value method有啥区别啊，算法都是一样的啊。。。。。
：代表波动率，那么就是波动率越大，其他因子不变-->HC越低，这个人的便“死不足惜”，于是life insurance可以少买。
