Answer:
The annual rate of return on this investment is 8.29%
Explanation:
The computation of the rate of return on this investment is shown below:
Since the copper penny is in 1795 is 1 cent
And,
1 cent = .01 dollars
Now
Year 1796 2018
Amount (in dollars) 0.01 $390,000
We know that
Future Value = Present Value × ((1 + rate )^time period)
Here,
t = 2018 - 1795 = 222
So,
.01 × ((1+rate)^(222)) = $480,000
(1+rate)^(222) = $48,000,000
1 + rate = $48,000,000^(1 ÷ 222)
1 + rate = $48,000,000^(0.004505)
1+rate = 1.082929503
rate = 0.082929503
Hence, The annual rate of return on this investment is 8.29%
