The population of the town has been growing for about 2 years Given the equation that represents the situation expressed as:

[tex]20,000e^{0.15t}=28000[/tex]

where t is the time taken.

To get the value of t;

[tex]20,000e^{0.15t}=28000\\e^{0.15t} = \frac{28000}{20000} \\e^{0.15t} = 1.4[/tex]

Take the ln of both sides

[tex]ln e^{0.15t}=ln1.4\\0.15t=0.3365\\t = \frac{0.3365}{0.15}\\t= 2.24years[/tex]

This shows that the population of the town has been growing for about 2 years
