Percentage change is often required to utilise figures provided in case studies and present them as evidence, or to use in other calculations.

For example:

If you were asked to calcuate the percentage change in output, from 460,000 units to 520,000 units.

The calculation is: change between values ​ x100

                                      original value

Change between values= 520,000- 460,000= 60,000

You then insert this figure into the calculation.

60,000

460,000

You can remember this as ​different ​value, goes above ​original; ​because d is before o in the alphabet.

And then always multiply by 100 as this figure is a percentage.

So the answer is 13%
