| \(£6 - £5.64 = 36\text{p}\) or \(50\text{p} - 47\text{p} = 3\text{p}\) | 6.4 | P1 | for a strategy to compare the same number of bottles e.g. \(£5.64 \div 12\) (\(= 47\) or 0.47) or \(12 \times 50\text{p}\) (\(= 6\) or 600) or 36 or 0.36 or 3 or 0.03 |
| P1 | for start of process to find percentage profit e.g. \(\dfrac{\text{``}36\text{''}}{564}\) or \(\dfrac{\text{``}3\text{''}}{\text{``}47\text{''}}\) or \(\dfrac{\text{``}6\text{''}}{5.64}\) or \(\dfrac{50}{\text{``}47\text{''}}\) oe with consistent units | ||
