Answer: The fox population decrease 1.298% every month.
Step-by-step explanation:
Since we have given that
Initial foxes = 170000
Every 7 months, the population loses [tex]\dfrac{1}{11}[/tex]
So, we need to find the rate of change in population every month.
So, we will use "Unitary method":
So, In every month, the population loses [tex]\dfrac{1}{11}\times \dfrac{1}{7}=\dfrac{1}{77}[/tex]
So, the percentage would be
[tex]\dfrac{1}{77}\times 100=1.298\%[/tex]
Hence, the fox population decrease 1.298% every month.
