The formula y = 13(1.32) gives the number of cellular phone users y (in millions) in some country for the years 1994 through 2006. In this formula, x = 0 corresponds to 1994, X = 1 corresponds to 1995, and so on. Use this model to predict the number of cellular phone users in the year 2007. million. The predicted number of cellular phone users in the year 2007 is (Round to the nearest whole number as needed.) 480 510 490 450 360
