Answer:
.
Explanation:
It is given that,
Initial population of a town = 2000
Growth rate = 4% = 0.04 per year
The exponential growth function for population is
![P=P_0(1+r)^t](https://img.qammunity.org/2021/formulas/mathematics/college/3sld4nreubu0rvhqiv0y0w5lyom8f8bymm.png)
where,
is initial population, r is growth rate and t is number of years.
Substitute
in the above equation.
![P=2000(1+0.04)^t](https://img.qammunity.org/2021/formulas/mathematics/college/ci2v47w0ke33em8mqazej3j6wlxx98g96p.png)
![P=2000(1.04)^t](https://img.qammunity.org/2021/formulas/mathematics/college/dllok2ip0mejucplhbedbolqzqmwyavant.png)
Therefore, the required equation is
, where P is population after t years.
