Answer:
-0.06 or -6%
Explanation:
The duration 't' of his investment is determined by subtracting the selling year by the purchasing year:
[tex]t = 2003-200 = 3\ years[/tex]
The future value ($10,361,500) of this original investment ($12,700,500) at a rate 'r' for a period of 3 years is given by:
[tex]10,361,500=12,477,500*(1+r)^3\\r=\sqrt[3]{\frac{10,361,500}{12,477,500}} -1\\r=-0.06[/tex]
His annual rate of return was -0.06 or -6%.
*Since he had a negative rate of return, the previous owner lost money in this investment
