At a certain interest rate, the present value of the following two payment patterns are equal:
(i) $ 700 at the end of five years, plus $ 2300 at the end of ten years,
(ii) $ 2060 at the end of five years.
At the same interest rate, $ 100 invested now, plus $ 120 invested at the end of five years will accumulate to P at the end of ten years. Calculate P.
P = $
