Given:
The annual average high temperature in a town was 50° in the year 2008.
The annual average high temperature in a town was 55° in the year 2009.
To find:
The percent increase in average high temperature in this town between the two years.
Solution:
The percent increase formula:
[tex]\%\text{ Increase}=\dfrac{\text{New value - Initial value}}{\text{Initial value}}\times 100[/tex]
Substitute new value = 55 and initial value = 50 in the above formula.
[tex]\%\text{ Increase}=\dfrac{55-50}{50}\times 100[/tex]
[tex]\%\text{ Increase}=\dfrac{5}{50}\times 100[/tex]
[tex]\%\text{ Increase}=\dfrac{1}{10}\times 100[/tex]
[tex]\%\text{ Increase}=10[/tex]
Therefore, the temperature in this town between the two years increased by 10%.
