| 3.3(0) | P1 | for a process to find cost of 1 kg of carrots, eg \(1.80 \div 3\ (= 0.60)\) |
| P1 | for a start to a process to find cost of 1 kg of potatoes, eg \(3.45 - 2 \times \text{``}0.60\text{''}\ (= 2.25)\) or \((1.80 + 3.45) \div 5\ (= 1.05)\) OR for a process to find the cost of 4 kg of carrots, eg \(\text{``}0.60\text{''} \times 4\ (= 2.40)\) | |
| P1 | (dep on P2) for a complete process to find the cost of 4 kg of carrots and the cost of 2 kg of potatoes, eg \(\text{``}0.60\text{''} \times 4\ (= 2.40)\) and \((\text{``}2.25\text{''} \div 5) \times 2\ (= 0.90)\) or \(\text{``}0.60\text{''} \times 4\ (= 2.40)\) and \((\text{``}1.05\text{''} - \text{``}0.60\text{''}) \times 2\ (= 0.90)\) | |
