Answer:
Rate of return is 2.52%
Explanation:
Investment in 1925 = $10,000
Portfolio value in 2000 = $64,402.23
Number of years = 2000-1925 = 75 years
Rate of return = ?
Using following formula to calculate rate of return.
A = P x ( 1 + r )^n
64,402.23 = 10,000 x ( 1 + r )^75
64,402.23 / 10,000 = ( 1 + r )^75
6.440223 = ( 1 + r )^75
[tex]\sqrt[75]{6.440223} = \sqrt[75]{(1+ r)^75}[/tex]
1.02515 = 1 + r
r = 1.02515 - 1
r = 0.02515
r = 2.52%
