| Answer | Mark | Mark scheme |
|---|---|---|
| 12.85 or 12.86 or 13.5(0) | P1 | for \(9 + 2 + 1\ (= 12)\) |
| P1 | for working out how many lots of 175 g are needed eg \(6000 \div \text{``}12\text{''} \times 2 \div 175\ (= 5.71...)\) | |
| P1 | for a complete process eg \(\text{``}5.71...\text{''} \times 2.25\ (= 12.857...)\) | |
| A1 | for 12.85 or 12.86 or 13.5(0) |
Additional guidance
Award this mark for sight of 4500, 1000 or 500
Process may lead to 5 or 6 instead of 5.71...
