Answer:
The growth rate is 35%
Explanation:
We are given that the amount of people in a population can be determined by using the model :

Formula of exponential growth :

Where y is the population in t years
a = Initial population
r = growth rate
The given equation can be written as

Om comparing it with 1
r = 0.35
So, Growth rate = 35%
Hence The growth rate is 35%
