问题如下：
Lucy believes that after retirement she will need about $2 million totally for her daily expenses. At present, she has $1million investment at a stated annual interest rate of 2.5%. Assuming compounded daily, how long does it take for Lucy to have enough money for retirement life?
选项：
A.27.73 years
B.28.07 years
C.26.48 years
解释：
A is correct.
EAR=(1+0.025/365)365-1=0.02531
$1million*(1+0.02531)N =$2million, N=27.73 years.
老师你好请问这题的计算器按法在计算器视频的第几分钟呢，谢谢
