标题: zai xian deng ...zhaoji !!!!

存款题,变脸。初始金额2000,n代表年数,则金额为P=2000(1+0.05%)^n. 问怎么能判定n more then 4?
    (1)p>2100(2)p<3000, key:A

which one is correct? iwanna to choose E

why E?

A seems to be ok.

if n=4, p should be around 2004,P>2100 it is ok to judge...

I think it is 5% not 0.05%, so 2000*(1+0.05)^4≈2000*1.2=2400
So, I vote for E
