Answer 1

$a)~Numarul~maxim~de~locuitori~este~36170,~inregistrat~in~anul~ \\ 1992. \\ b)~Numarul~minim:~10913. \\ c)~In~2011~populatia~era~28102. \\ \\ 36170- \frac{p}{100} \cdot 36170=28102 \\ \\ 36170(1- \frac{p}{100})=28102 \\ \\ 1- \frac{p}{100} = \frac{28102}{36170} \\ \\ 1- \frac{p}{100}= \frac{14051}{18085} \\ \\ \frac{p}{100}=1- \frac{14051}{18085 }$

$\frac{p}{100}= \frac{4034}{18085} \Rightarrow p= \frac{100 \cdot 4034}{18085} \approx 22,3 . \\ \\ Deci~numarul~de~locuitori~a~scazut~cu~22,3 \%.$
