Answer 2

present population is 395808

Step-by-step explanation:

given

population (p) = 375000

rate (R) = 2%

time (T) = 3yrs

out - migration (o) = 875

in-migration (I) = 1480

death (D) = 2750

pt = ?

we know,

pt = p(1+R\100)^T + in mig. - out mig - death

= 375000(1+2\100)^3 + 1480 - 875 - 2750

=375000(1.02)^3 -2,145

= 375000 x 1.061208 - 2145

=39,7953 - 2145

=395,808

so, present population is 395808
