Step-by-step explanation:
percent increase = [tex]\frac{increase}{original}[/tex] × 100%
the increase = 421 - 376 = 45, hence
percent increase = [tex]\frac{45}{376}[/tex] × 100% ≈ 12%
The percentage increase in the population of the chilrden since past year is [tex]11.96\%[/tex].
According to the question, the town's population of children increased from 376 to 421 during the past year.
So, the increase in the population of the children is-
[tex]Increase=421-376\\Increase=45[/tex]
Now, the percentage increase in population of the children per year is calculated as-
[tex]Percentage\;Increase=\dfrac{Increase}{376}\times 100\%\\Percentage\;Increase=\dfrac{45}{376}\times 100\%\\Percentage\;Increase=0.1196\times 100\%\\Percentage\;Increase==11.96\%[/tex].
