| Answer | Mark | Mark scheme |
|---|---|---|
| 180.9 | P1 | for starting to work with proportion eg. \(60 \div 100\ (= 0.6)\) or \(150 \div 100\ (= 1.5)\) OR \(100 \div 60\ (= 1.66..)\) or \(100 \div 150\ (= 0.66..)\) OR \(84 \div 100\ (= 0.84)\) or \(87 \div 100\ (= 0.87)\) or \(84 \div 10\ (= 8.4)\) or \(87 \div 10\ (= 8.7)\) or \(84 \div 2\ (= 42)\) or \(87 \div 2\ (= 43.5)\) OR \(100 \div 84\ (= 1.19..)\) or \(100 \div 87\ (= 1.14..)\) |
| P1 | for a complete process to work out the calories in either item eg. \(\text{``}0.6\text{''} \times 84\ (= 50.4)\) or \(\text{``}1.5\text{''} \times 87\ (= 130.5)\) OR \(84 \div \text{``}1.66..\text{''}\ (= 50.4)\) or \(87 \div \text{``}0.66..\text{''}\ (= 130.5)\) OR \(\text{``}0.84\text{''} \times 60\ (= 50.4)\) or \(\text{``}0.87\text{''} \times 150\ (= 130.5)\) or \(\text{``}8.4\text{''} \times 6\ (= 50.4)\) or \(\text{``}8.7\text{''} \times 15\ (= 130.5)\) or \(\text{``}42\text{''} \times 6 \div 5\ (= 50.4)\) or \(\text{``}43.5\text{''} \times 3\ (= 130.5)\) OR \(60 \div \text{``}1.19..\text{''}\ (= 50.4)\) or \(150 \div \text{``}1.14..\text{''}\ (= 130.5)\) | |
| P1 | (dep on P2) for a complete process to find total number of calories in the breakfast, eg. \(\text{``}50.4\text{''} + \text{``}130.5\text{''}\) | |
| A1 | for 180.9 or 181 |
