Question

A town’s population of children increased from 376 to 421 during the past year.

Answer 1

The equation shows how to find the percent increase:

$Percent\ increase = \frac{421-376}{376} \times 100$

Solution:

Given that,

A town’s population of children increased from 376 to 421 during the past year

To find: percent increase

The percent increase is given by formula:

$\text{Percent increase} = \frac{\text{Final value - initial value}}{\text{initial value}} \times 100$

From given,

Initial value = 376

Final value = 421

$Percent\ increase = \frac{421-376}{376} \times 100\\\\Percent\ increase = \frac{45}{376} \times 100\\\\Percent\ increase = 11.968 \%$

Thus the equation is found and solved
