Respuesta :

Answer:

Option(b)

Step-by-step explanation:

Let the population in 2022 will be x

Declining rate=2.2%

Population in 2016 year=3500

According to question

x=3500[tex](100-\frac{2.2}{100}[/tex])^{6}

x=3500[tex](\frac{1000-22}{1000}[/tex])^{6}

x=3500[tex](\frac{978}{1000}[/tex])^{6}

x=3500.978^{6}

x=3063
