The correct Answer is:
To find the population of a town a year ago, given that the population increases by 6% annually and the current population is 17,490, we can follow these steps:
### Step-by-Step Solution:
1. **Understand the relationship between last year's population and this year's population**:
- If the population increases by 6%, it means that this year's population is 106% of last year's population.
- We can express this mathematically as:
\[
\text{Current Population} = \text{Last Year's Population} \times \left(1 + \frac{6}{100}\right)
\]
- This simplifies to:
\[
\text{Current Population} = \text{Last Year's Population} \times 1.06
\]
2. **Set up the equation**:
- Let \( P \) be the population a year ago. Then, we can write:
\[
17,490 = P \times 1.06
\]
3. **Solve for last year's population \( P \)**:
- To find \( P \), we need to divide both sides of the equation by 1.06:
\[
P = \frac{17,490}{1.06}
\]
4. **Calculate the value**:
- Performing the division:
\[
P = \frac{17,490}{1.06} \approx 16,500
\]
5. **Conclusion**:
- Therefore, the population of the town a year ago was approximately 16,500.
### Final Answer:
The population of the town a year ago was **16,500**.
