Step-by-step explanation:
Here, the number of people has beed increased.
→ Number of people increased = 71 - 48
→ Number of people increased = 23
[tex] \to \% \: change = \left ( \dfrac{23}{71} \times 100 \right ) \: \% \\ [/tex]
[tex] \to \% \: change = \left ( \dfrac{2300}{71} \right ) \: \% \\ [/tex]
[tex] \red{ \to \% \: change = 32.39 \: \%} \\ [/tex]
Therefore, percentage change is 32.39 %.
