Answer 1

To calculate the percent of change in population from Town A from 2010 to 2020, we can use the formula you provided:

$$\text{Percent Change}=\frac{\text{new value}-\text{old value}}{\text{old value}}\times 100$$

In this case:

• New value (2020 population) = 18,560
• Old value (2010 population) = 12,979

Now, we can substitute these values into the formula:

$$\text{Percent Change}=\frac{18,560-12,979}{12,979}\times 100$$

Calculating the change: $$18,560-12,979=5,581$$

Now substituting this back into the equation: $$\text{Percent Change}=\frac{5,581}{12,979}\times 100$$

Now, calculate the fraction: $$\frac{5,581}{12,979}\approx 0.4301$$

Now multiply by 100 to get the percentage: $$0.4301\times 100\approx 43.01$$

Rounding to the nearest whole percentage point gives us 43%.

So, the percent of change in population from 2010 to 2020 is a 43% increase.
