Answer:
His annual rate of return on this sculpture was -2.856%.
Explanation:
FV= PV x [tex]{(1+r)^{t}[/tex] -----(a)
FV – amount returned,
PV - amount invested,
r – annual rate of return,
t – number of years.
t = 2015 - 2009 = 6
Re-arranging the equation (a) we get,
r = [tex](\frac{FV}{PV})^{\frac{1}{t} } -1[/tex]
r = [tex](\frac{10,689,500}{12,719,500} )^{\frac{1}{6} } -1[/tex]
r = 0.0285 or -2.856%
