In the years after warning labels were put on cigarette packs, the number of smokers
Chapter 6, Problem 108(choose chapter or problem)
In the years after warning labels were put on cigarette packs, the number of smokers dropped from approximately two in five adults to one in five. The bar graph shows the percentage of American adults who smoked cigarettes for selected years from 1970 through 2010.
The mathematical model
\(p+\frac{x}{2}=37\)
describes the percentage of Americans who smoked cigarettes, p, x years after 1970. Use this model to solve Exercises 107–108.
a. Does the mathematical model underestimate or overestimate the percentage of American adults who smoked cigarettes in 2000? By how much?
b. Use the mathematical model to project the year when only 2% of American adults will smoke cigarettes.
