Answer:
1,802,863
Step-by-step explanation:
Initial population of state = 1,821,000
Decay rate = 0.2% = 0.002
Time = 5 years
The exponential decay function is

where, a is initial value, r is decay rate and t is time in years.
Substitute a=1,821,000 and r=0.002 in the above function.


The population function is
.
Substitute t=5 in the above function.



Therefore, the population after 5 years is 1,802,863.
