Answer

Determine the sinking fund deposit by using a 30-year annuity-due accumulation factor (the sinking fund must accumulate to $500,000 after 30 years). The 10 th deposit will be made at time 9 , so you want the sinking fund balance at time 9. Use the sinking fund deposit and a 9 -year annuity-due accumulation factor to determine the balance.

[[math]] 500000=D \ddot{s}_{\overline{30} \mid .1} \text { so } D=500000 / \ddot{s}_{\overline{30} \mid}=500000 / 180.943425=2763.29466 [[/math]]

The amount immediately prior to the tenth deposit will be the accumulated amount including the tenth deposit less the tenth deposit. i.e.

[[math]] D s_{\overline{10} \mid i=.10}-D=D\left(s_{\overline{10} \mid i=.10}-1\right)=2763.29466(15.93742-1)=41276.51 [[/math]]
