Certainly! To solve this problem, we need to calculate the future population of the town based on exponential growth, using the formula for compound interest.

The formula for compound growth is:

\(\[ P = P_0 \times (1 + r)^t \]\)

where:
- \(\( P \)\) is the future population.
- \(\( P_0 \)\) is the initial population.
- \(\( r \)\) is the annual growth rate.
- \(\( t \)\) is the number of years.

Given:
- Initial population (\(\( P_0 \)\)) = 14,000
- Annual growth rate (\(\( r \)\)) = 0.05 (which is 5%)
- Number of years (\(\( t \)\)) = 14

Let's calculate step-by-step:

1. Initial Population: \(\( P_0 = 14,000 \)\)
2. Growth Rate: \(\( r = 0.05 \)\)
3. Number of Years: \(\( t = 14 \)\)

Plug these values into the formula:

\(\[ P = 14,000 \times (1 + 0.05)^{14} \]\)

First, calculate \(\( 1 + 0.05 \)\):

\(\[ 1 + 0.05 = 1.05 \]\)

Next, raise 1.05 to the power of 14:

\(\[ 1.05^{14} \approx 1.979 \]\)

Now, multiply this result by the initial population:

\(\[ P \approx 14,000 \times 1.979 \]\)

\(\[ P \approx 27,706 \]\)

Hence, the population after 14 years, rounded to the nearest whole number, will be approximately 27,706.
