$\text{percentage change} = \frac{\text{new value} - \text{original value}}{\text{original value}} \times 100$

What are the steps to set out a calculate answer?

e.g. revenue rises from £200 to £250 — calculate the percentage change

1. Write the formula: $\frac{\text{new} - \text{original}}{\text{original}} \times 100$.
2. Substitute and work through: $\frac{250-200}{200} \times 100$.
3. State the answer with its unit: $25\%$ increase.

True or false? If your final figure is wrong you automatically score zero on a calculate question.

False. Correct working can still earn method marks.

The value has fallen — say so in your answer (e.g. 'a 10% decrease').

Which units should be attached to a business calculation answer?
