What is Percentage?
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Given that;
Previous price of gas per month= $125
New price of gas per month= $ 150
Now,
Increase in price of gas bill = Previous price - New price
= $ 150 - $125
= $25
So, The percent increase of gas bill will be calculated as;
Percent increase = Increased price / Actual price x 100
= $25 / $125 x 100
= 1/5 x 100
= 20%
So, Increase in percent = 20%.
Thus, Increase percent on gas bill is 20%.
