The city 3

The city has 22,000 residents. How long it is expected to have 25,000 residents if the average annual population growth is 1.4%?

Result

n =  9.195

Solution:

(1+1.4/100)n=25000/22000 1.014n=25/22 nln⁡1.014=ln⁡25/22 n=ln⁡25/22ln⁡1.014=9.195 (1+1.4/100)^n = 25000/22000 \ \\ 1.014^n = 25/22 \ \\ n \ln 1.014 = \ln 25/22 \ \\ n = \dfrac{ \ln 25/22 }{ \ln 1.014 } = 9.195 \ \\
