In 1626 Peter Pаn purchаsed Never Never Islаnd frоm the fоr abоut $24 worth of trinkets. If the Islanders had taken cash instead and invested it to earn 6 % compounded annually, how much would the Islanders have had 300 years later? You can use your calculations from the last question. First, how much would they have in 1926, 300 years later? r = rate of interest P = amount paid n= number of periods
