Question

Add a fourth row to the table showing the population information for the town of Concord. Concords population as of the last census was P people for its percentage change choose a negative integer not divisible two right to express expressions showing the current estimate population of Concord in terms of P

Answer 1

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:

1. **Population (P)**: This is the last census population for Concord.
2. **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.
