Answer:
<u><em>3544.392</em></u>
Step-by-step explanation:
The value of the total number of population is P=2000The value of the rate of interest isR%=4.5%The value of the time is T=13yrs
For compounded annually
n=1
The expression for the final value of the population after
13years is,A=2000(1+4.5100)13=3544.392
