101.4 - 97.5
101.4 x 0.0390 = 3.9%

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.
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.
