just solve
2.903 t - 1.98 = 18
when you get t, add that to 2000
such bogus wordage. 4 <= t <= 9 is the condition.
the annual sales S (in billion of dollars) of oracle corporation from 2004 through 2009 can be approximated by the linear equation S= 2.903t-1.98, 4 is less than proximally T less than proximally 9, where t represents the year, with t=. use the model to 4 corresponding to 2004. use the model to estimate the year in which Oracle's annual sales were about 18 million.
