Final answer:

To calculate the percentage change, subtract the old value from the new value, divide it by the old value, and multiply by 100%.

Step-by-step explanation:

To find the percentage change, we can use the formula:

Percentage change = (New value - Old value) / Old value * 100%

In this case, the old value is £80 and the new value is £100.

Substituting these values into the formula, we get:

Percentage change = (£100 - £80) / £80 * 100%

Simplifying, we get:

Percentage change = £20 / £80 * 100%

This can be further simplified to:

Percentage change = 0.25 * 100%

Therefore, the percentage change is 25%.
