from 125 to 150 is just 25 units.
now if we take 125 to be the 100%, what is 25 off of it in percentage?
[tex]\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 125&100\\ 25&x \end{array}\implies \cfrac{125}{25}=\cfrac{100}{x}\implies 5=\cfrac{100}{x} \\\\\\ x=\cfrac{100}{5}\implies x=20[/tex]
Answer: 20%
Step-by-step explanation:
Given : Previous price of gas per month= $125
New price of gas per month= $ 150
Then,
Increase in price of gas = Previous price - New price
= $ 150 - $125 = $25
Now , the percent increase of your gas bill will be :_
[tex]\dfrac{\text{Increase in price }}{\text{Previous price}}\times100\\\\=\dfrac{25}{125}\times100\\\\=20\%[/tex]
Hence, the percent increase of your gas bill = 20%
