下面是2007 L3 真题里面的一段话：

The Ingrams are meeting with Caleb Swann, CFA, their long-time advisor, to discuss financial
planning issues. The Ingrams agree that their current annual pre-tax income need is C$200,000.
The Ingrams expect that their inflation-adjusted expenses will remain constant during retirement.
They plan to fund their living expenses by taking annual distributions from their portfolio with
the first distribution to occur immediately. Swann believes an appropriate long-term inflation
rate is 2.5 percent and an appropriate planning horizon is 35 years.

上面标红的句子，是不是代表他们每年的费用都是200000*1.025=205000，还是以后每年的费用都要乘以inflation(1.025).

还有就是算nominal return时直接用r+i和(1+r)*(1+i)-1的区别？

谢谢
