Re: [問題] EA-1 Segment A, Joint Board for Enro …
我的答案是$75.87311
@ 2000 1/1 cost of perp. =1100 = 100/i*(1+i) i=10%
@ 2014 1/1 after 1st pmt so the remaining value = 1100-100=1000
accumulate to 2018 1/1 1000*(1+0.5i)^4 = 1215.506
@ 2018 1/1 the value of ann. due = pmt * [1-(1+j)^(-20)]/j * (1+j)
where 1+j= (1+0.5i)^0.5 j=2.46951%
set 1215.506 = pmt * [(1+j)^(-20)]/j * (1+j)
so I get pmt = $75.87311
cheers ^_^
