The correct Answer is:
To find the population of the city two years ago, we can work backwards from the current population using the percentage increase. ### Step-by-Step Solution: 1. **Understand the Current Population**: The current population of the city is given as 338,000. 2. **Identify the Percentage Increase**: The population increases by 30% each year. This means that each year, the population is multiplied by 1.30 (which is 100% + 30%). 3. **Calculate the Population One Year Ago**: To find the population one year ago, we can divide the current population by 1.30: \[ \text{Population one year ago} = \frac{338,000}{1.30} \] \[ = 260,000 \] 4. **Calculate the Population Two Years Ago**: Now, we need to find the population two years ago. We will again divide the population one year ago by 1.30: \[ \text{Population two years ago} = \frac{260,000}{1.30} \] \[ = 200,000 \] 5. **Final Answer**: Therefore, the population of the city two years ago was 200,000. ### Summary: The population of the city two years ago was **200,000**.

To find the population of the city two years ago, we can work backwards from the current population using the percentage increase. ### Step-by-Step Solution: 1. **Understand the Current Population**: The current population of the city is given as 338,000. 2. **Identify the Percentage Increase**: ...
