Given parameters:
Initial value = 27
Final value = 31
Unknown:
Percentage change = ?
Solution:
The percentage change is the difference between the final and initial value divide by the initial value multiplied by 100;
Percentage change = [tex]\frac{Final value - Initial value}{Initial value} x 100[/tex]
Input the parameters and solve;
Percentage change = [tex]\frac{31 - 27}{27} x 100[/tex]
= 14.8%
The percentage change is 14.8%. This is an increase because the value move from 27 to 31.
