Answer: The rate of change in population is 100 per year.
Step-by-step explanation:
Since we have given that
In 1993, the population = 4730
In 1997, the population = 4330
So, it means, population continues to change linearly.
So, the slope of population to get change would be
[tex]\dfrac{4730-4330}{1997-1993}\\\\=\dfrac{400}{4}\\\\=100[/tex]
Hence, the rate of change in population is 100 per year.
