To create a fourth row for the town of Concord in your table of population data, we first need to establish the information you provided. Let's use the following example:
- Population (P): This is the last census population for Concord.
- Percentage Change: We'll choose a negative integer not divisible by 2. For this example, let's use -15.
Given these parameters, we can express the current estimated population of Concord. The population after a percentage decrease can be calculated using the formula:
\[ \text{Current Population} = P \times \left(1 + \frac{\text{Percentage Change}}{100}\right) \]
Substituting in our percentage change:
\[ \text{Current Population} = P \times \left(1 - 0.15\right) \] \[ \text{Current Population} = P \times 0.85 \]
Now, we can create the fourth row of the table in this form:
| Town | Population | Percentage Change | Current Estimated Population | |-----------|------------|-------------------|------------------------------- | | Example 1 | X | Y | \( X \times (1 + \frac{Y}{100}) \) | | Example 2 | Z | W | \( Z \times (1 + \frac{W}{100}) \) | | Example 3 | Q | R | \( Q \times (1 + \frac{R}{100}) \) | | Concord | P | -15% | \( P \times 0.85 \) |
This row effectively conveys the population information for Concord, indicating how it has changed since the last census.
