✔ 最佳答案
Compound Interest

Amount = Principal × (1 + Rate/Freq)^(Freq × Time)

Principal = $20,000
Rate = 8% p.a.
Compounding frequency = 4 times per year
Time = 1 year

Amount
= $20,000 × ( 1 + 8%/4 )⁴
= $20,000 × ( 1 + 2% )⁴
= $20,000 × ( 1.02 )⁴
= $21,648.6432

well...it's always gd if you know sth. by your logical thinking ....but is it possible that if I can tell the manager that if he can adjust the system to show all the reporters ' names and the reasons ...not always others for reasons
it's truly unacceptable ......
