Percentage increase in the price of gas rounded to the nearest tenth in 13.8%
Solution:
Percent increase and percent decrease are measures of percent change, which is the extent to which a variable gains or loses value
The figures are arrived at by comparing the initial (or before) and final (or after) quantities according to a specific formula.
The formula for percentage increase\decrease is given as:
[tex]\text { percentage increase } \backslash d e c r e a s e=\frac{\text { final value-initial value}}{\text { initial value }} \times 100[/tex]
If the result is positive, it represents increase in percentage
If the result is negative, it represents decrease in percentage
Given that I noticed that gas was $2.18 a gallon
On my way back home, the gas was $2.48 a gallon
So here initial value = 2.18 and final vlaue = 2.48
[tex]\begin{array}{l}{\text { percentage increase }=\frac{2.48-2.18}{2.18} \times 100} \\\\ {\text { percentage increase }=0.1376 \times 100=13.76 \%}\end{array}[/tex]
Thus % increase in the price of gas rounded to the nearest tenth in 13.8%
