Question

Find the percent change. State whether it is an increase or decrease. Round to the nearest tenth of a percent. From 27 to 31

Answer 1

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  = $\frac{Final value - Initial value}{Initial value} x 100$

  Input the parameters and solve;

  Percentage change = $\frac{31 - 27}{27} x 100$  

                                    = 14.8%

The percentage change is 14.8%. This is an increase because the value move from 27 to 31.
