Question 251940: The consumption of cigarettes is declining. If t represents the number of years since 1985, then the consumption, C, is modeled by

C=-14.25t+598.69
200=-14.25t+598.69
-14.25t=200-598.69
-14.25t=-398.69
t=-398.69/-14.25
t=27.98 or 28 years.
1985+28=2013 is the projected year for 200,000,000 smokers.
