Answer: 1623
Explanation:
Given: The population of deer in a state = 1500
The growth rate =2%=0.02
Time period = 4 years
We know that the exponential growth function is represented by

where, A is the initial amount, r is the growth rate and x is the time period.
Here A =1500 r=0.02 and x=4 years
Thus, the population after 4 years=

[because the number of dear cannot be in decimal]
hence. the population after 4 years= 1623
