| Answer | Mark | Mark scheme |
|---|---|---|
| 180, 300, 75 | M1 | for complete method to find amount needed for 30 biscuits for one ingredient, eg \(120 \div 20 \times 30\ (= 180)\) oe eg \(120 + 120 \div 2\ (= 180)\) or for method to find a scale factor, eg \(30 \div 20\ (= 1.5 \text{ oe})\) or for method to find amount needed for 10 biscuits for at least 2 ingredients eg \(120 \div 2\ (= 60)\) or \(200 \div 2\ (= 100)\) or \(50 \div 2\ (= 25)\) or for method to find amount needed for 1 biscuit for at least 2 ingredients eg \(120 \div 20\ (= 6)\) or \(200 \div 20\ (= 10)\) or \(50 \div 20\ (= 2.5)\) |
| M1 | for complete method to find amount needed for 30 biscuits for at least 2 ingredients, eg at least 2 of \(120 \div 20 \times 30\ (= 180)\) or \(200 \div 20 \times 30\ (= 300)\) or \(50 \div 20 \times 30\ (= 75)\) oe or eg at least 2 of \(120 \times \text{``}1.5\text{''}\ (= 180)\) or \(200 \times \text{``}1.5\text{''}\ (= 300)\) or \(50 \times \text{``}1.5\text{''}\ (= 75)\) or eg at least 2 of \(120 + \text{``}60\text{''}\ (= 180)\) or \(200 + \text{``}100\text{''}\ (= 300)\) or \(50 + \text{``}25\text{''}\ (= 75)\) or eg at least 2 of \(30 \times \text{``}6\text{''}\ (= 180)\) or \(30 \times \text{``}10\text{''}\ (= 300)\) or \(30 \times \text{``}2.5\text{''}\ (= 75)\) | |
| A1 | for all quantities correct |
