Question: if the 2007 year shows the same rate of change as 2006 , what would the projected ending cash flow balance be , in millions?
Evidence:
table_13: ( in millions ) the end of year of 2006 is $ 8518 ; the end of year of 2005 is $ 10601 ; the end of year of 2004 is $ 6415 ;
Program: divide(8518, 10601), multiply(#0, 8518)
