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 =
`(Final value - Initial value)/(Initial value) x 100`

Input the parameters and solve;

Percentage change =
`(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.
