Alex deposited x dollars into a new account that earned 8 percent annual interest, compounded annually. One year later Alex deposited an additional x dollars into the account. If there were no other transactions and if the account contained w dollars at the end of two years, which of the following expresses x in terms of w ?
请问，这道题里的at the end of two years, 是从第一笔后两年，还是第二笔后两年？ 表述上有什么不同。作者: nianbohu 时间: 2013-4-10 21:12
one yr later 指的就是第2年
in ur words, 即是从第一笔后两年。
ans: x = w/(1.08+1.08^2)

hmm...to be more accurate...
1.08+(1.08)^2作者: headhunter 时间: 2013-4-11 21:04
