Problem #$9($Perpetuities$)$: An investor purchasing a British consol is entitled to receive annual payments from the British government forever. What is the price of a consol that pays $$125$ annually if the next payment occurs one year from today? The market interest rate is $3\mathrm{.}9$ percent.

Professor Cursio adds: Ignore the fact that the British government is paying in US dollars and not UK pounds. Pretend this is actually true.
