Answer:
-5.95%
Explanation:
A = P(1+r)^n
A is the auction price at which the sculpture was sold = $10,331,500
P is the price the sculpture was purchased = $12,417,500
n is the time interval between the year of sales and year of purchase
10,331,500 = 12,417,500(1+r)^3
(1+r)^3 = 10,331,500/12,417,500
(1+r)^3 = 0.832
1+r = (0.832)^1/3
1+r = 0.9405
r = 0.9405 - 1 = -0.0595 = -5.95%
