Question

13. Austria has a population of 8.747 million people in 2016. The country holds the record for the highestpercentage of individuals in a country that are smokers. If 3.175 million people of the country smoke, whatpercentage of the total population is this rounded to the nearest tenth?14. The strongest beer ever sold named “The End of History" contains 55% alcohol content (sold in July 2010). Whatamount of alcohol is in each bottle of 16 oz beer?

Answer 1

The total population of people in the country is

`\begin{gathered} =8.747\text{million people} \\ =8.747*1000000 \\ =8,747,000\text{ people} \end{gathered}`

The number of people that smokes is

`\begin{gathered} =3.175\text{million people} \\ =3.175*1000000 \\ =3,175,000\text{ people} \end{gathered}`

The formula for the percentage of people that smoke is

`\text{ percentage smokers}=\frac{\text{ population of smokers}}{\text{total population}}*100\text{ \%}`

By substituting the values, we will have

`\begin{gathered} \text{ percentage smokers}=\frac{\text{ population of smokers}}{\text{total population}}*100\text{ \%} \\ \text{percentage smokers=}(3,175,000)/(8,747,000)*(100)/(1) \\ \text{percentage smokers}=(3,175,000)/(87,470)\text{ \%} \\ \text{percentage smokers}=36.298\text{ \%} \\ \text{percentage smokers}\approx\text{ nearest tenth 36.3\%} \end{gathered}`

Hence,

The final answer = 36.3%
