Answer 1

To calculate the percentage change when a price of £40 is increased to £70, we can use the following formula:

Percentage Change = (New Value - Old Value) / Old Value * 100

Plugging in the numbers:

Percentage Change = (£70 - £40) / £40 * 100 = £30 / £40 * 100 = 75%

So the price has increased by 75%.
