Answer:
His annual rate of return on this sculpture is -4.46%.
Step-by-step explanation:
let PV be the amount invested and after t periods it turns to be FV
FV = PV(1+r)^t
(1+r)^t = FV/PV
1 + r = (FV/PV)^(1/t)
r = (FV/PV)^(1/t) - 1
t is the number of years from 1999 to 2003, t = 2003 - 1999 = 4 years
FV = $10,311,500
PV = $12,377,500
r = ($10,311,500/$12,377,500)^(1/4) - 1
r = -0.0446
therefore, His annual rate of return on this sculpture is -4.46%.
