In 1867, the US Secretary of State purchased Alaska from Russia for $7,200,000 (about two cents per acre). At the time, the deal was considered a folly (i.e. crazy) but from our perspective today, did the US Secretary of State get a bargain? What would it cost in 2007 if Alaska was in exactly the same condition as it was 140 years before and the prevailing interest rate over the 140 years was 4%. Please show and explain your calculations,
