Suppose that a company's annual sales were $1,200,000 in 1999. The annual growth rate of sales from 1999 to 2000 was 16%, from 2000 to 2001 was -5%, and from 2001 to 2002 was 22%.The geometric mean growth rate of sales over this three-year period is calculated as 10.37%. Use the geometric mean growth rate and determine the forecasted sales for 2004.A. 1,780,678B. 1,200,014C. 1,965,337D. 1,613,371E. 1,422,197
