Given:

The percentage of age group smoking Marijuana is,

18-29 years = 22%

30-49 years = 11%

Over 65 = 3%

For the age group 30-49,


\begin{gathered} 11\text{ \% of 470 people smoke Marijuana} \\ (11)/(100)*470=51.7\approx52 \\ \text{The number of people dont smoke Marijuana is, } \\ 470-52=418 \end{gathered}

Total people smoke Marijuana is,


114+52+38+14=218

Total people don't smoke Marijuana is,


403+418+281+463=1565

Total people,


517+470+319+477=1783

The percentage of people who smoke Marijuana in the age group 50-64 is,


\begin{gathered} a\text{ \% of 319=38} \\ (a)/(100)*319=38 \\ a=38*(100)/(319) \\ a=11.91 \\ a\approx12\text{ \%} \end{gathered}

The percentage of people in the age group 50-64 who smoke Marijuana is,


a\text{ \% of 1783=319}
