麻烦解释一下， 不是很懂

问题如下：

A professional embarks on a project today, spanning three years. Her compensation arrangement includes the following payouts:

If she plans to invest these sums at an annual interest rate of 3%, compounded annually, until her retirement in 10 years, what is the approximate value at the end of 10 years?

选项：

A.

$618,994.00

B.

$566,467.60

C.

$460,590.00

解释：

For Year 1: $100,000 / (1 + 0.03)^1 = $97,087.38

For Year 2: $150,000 / (1 + 0.03)^2 = $141,389.39

For Year 3: $200,000 / (1 + 0.03)^3 = $183,028.33

Now, the sum of these present values is $97,087.38 + $141,389.39 + $183,028.33= $421,505.1.

If this amount is invested for 10 years at a 3% annual interest rate, the future value (FV) would be $421,505.1 * (1 + 0.03)^10 = $566,467.6.
