Question

"A judge denied a 94-year-old woman s attempt to force a Lottery Commission to pay her $4.58 million winnings up front on the grounds that she otherwise won't live long enough to collect it all. The woman already received an immediate payment of $108,555, and she will receive 22 annual gross checks of $203,248. If a buyer offers to pay the woman $2.3 million for the 22 annual gross checks of $203,248, what is the buyer's annual interest rate? Enter your answer as a percentage between 0 and 100."

Explanation / Answer

The rate of interest for 25 payments of 118173 each that has a present value of 2 million is given by

2 million = 118173 x (P/A, i%, 25)

16.92433974 = (P/A, i%, 25)

Trial and error gives interest rate i% = 3.25% Hence the buyer's annual interest rate is 3.25%
