write each increase or decrease as a percent.
the price of gasoline rose from 97.5/L to 101.4/L.
101.4 - 97.5
101.4 x 0.0390 = 3.9%
is this right?? im not really sure how to do this.sorry for all these questions.
To find the percent increase you need to divide the difference between it and the new number by the old number.
101.4 - 97.5 = 3.90
3.9 / 97.5 = 0.04 = 4%
To check it, multiply: 97.5 * 0.04 = 3.90
The price increased $3.90 which is a 4% increase.
