2. Change = 150 – 50 = 100
3. Formula: Can be implied Change/original × 100
4. (150-50)/50 × 100

6. [3] Correct answer: 200%
7. [2] Both of the following: Correct/implied formula AND Correct calculation of the change in total revenue (100) OR An incorrect answer with one mistake allowing OFR for final stage. For example, (150 – 50) / 150 × 100 = 100 / 150 × 100 = 66.67% (accept any figure between 66.6 and 67) – 2 marks, (wrong denominator)
