You just answered my question and #3 was the only correct answer, is there anyway you could redo #'s 1 and 2?

Thank you for the help as well

1.Annual rate of appreciation of the coin from its first minting to the 1971 sale

n = 1971 - 1794 = 177 FV = 305,000 PV = 5 305000 = 5 (1+r)^177 61000 = (1+r)^177 1+r = (61000)^(1177) r = 1.0642 - 1 = 0.0642 = 6.42%

2.Annual rate of 1971 buyer earn on his purchase

n = 2014 - 1971 = 43 FV = 1,965,500 PV = 305,000 1965500 = 305000 (1+r)^43 6.44 = (1+r)^43 1+r = (6.44)^(143) r = 1.0443 - 1 = 0.0443 = 4.43%

3.Annual rate of appreciation of the coin from its first minting to the 2014

n = 2014 - 1794 = 220 FV = 1,965,500 PV = 5 1965500 = 5 (1+r)^220 393100 = (1+r)^220 1+r = (393100)^(1220) r = 1.0603 - 1 = 0.0603 = 6.03%
