Although appealing to more refined tastes, art as a collectible has not always performed so profitably. during 2003, sotheby’s sold the edgar degas bronze sculpture petite danseuse de quatorze ans at auction for a price of $10,311,500. unfortunately for the previous owner, he had purchased it in 1999 at a price of $12,377,500. what was his annual rate of return on this sculpture? (a negative answer should be indicated by a minus sign. do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e. g., 32.16.)
