The population of the municipality in 1995 was approximately 1,750,000 people.

Solución

To determine the population of the municipality in 1995, we can use the information provided about the increase in population from 1995 to 1996. Given: - Population in 1996 = 1792851 - Increase in population from 1995 to 1996 = 2.35% Let's denote the population in 1995 as \( P_{1995} \). The increase in population from 1995 to 1996 can be calculated using the formula: \[ \text{Increase} = \text{Population in 1996} - \text{Population in 1995} \] Since the increase is 2.35%, we can set up the equation: \[ 2.35\% \times P_{1995} = 1792851 - P_{1995} \] Now, we can solve for \( P_{1995} \) to find the population of the municipality in 1995. Solve the equation by following steps: - step0: Solve for \(P_{1995}\): \(2.35\%\times P_{1995}=1792851-P_{1995}\) - step1: Calculate: \(0.0235P_{1995}=1792851-P_{1995}\) - step2: Move the variable to the left side: \(0.0235P_{1995}+P_{1995}=1792851\) - step3: Add the terms: \(1.0235P_{1995}=1792851\) - step4: Divide both sides: \(\frac{1.0235P_{1995}}{1.0235}=\frac{1792851}{1.0235}\) - step5: Divide the numbers: \(P_{1995}=\frac{3585702000}{2047}\) The population of the municipality in 1995 was \( \frac{3585702000}{2047} \) people.

The Deep Dive

To find the population of the municipality in 1995, we can set up the equation based on the information given. Let the population in 1995 be \( P \). According to the increase of \( 2.35\% \), we have: \[ P + (0.0235 \times P) = 1792851 \] This simplifies to: \[ 1.0235 \times P = 1792851 \] Now, divide both sides by \( 1.0235 \): \[ P = \frac{1792851}{1.0235} \approx 1750000 \] So, the population of the municipality in 1995 was approximately 1,750,000. The significance of knowing historical population figures can help in urban planning, resource allocation, and understanding growth trends over time. For example, city planners can analyze how the population change influences infrastructure needs, such as schools and hospitals. Understanding population dynamics isn’t just for researchers; it impacts businesses too! Companies might use population data to decide where to open new locations or how to target their marketing efforts. So, whether you’re an entrepreneur or a government official, demographic insights can shape better decisions!
