| Scheme | Marks |
|---|---|
| 18 000 + 14 × 1160 (= 34 240) oe or 18 000 + 16 240 (= 34 240) | M1 |
“34 240” – 32 000 (= 2240) or \(\dfrac{\text{“}34\,240\text{”}}{32\,000}\) (= 1.07) | M1 |
\(\dfrac{\text{“}2240\text{”}}{32\,000}(\times 100)\) or \(\dfrac{\text{“}34\,240\text{”}}{32\,000} \times 100\) (= 107) or “1.07” – 1 (= 0.07) | M1 |
| Correct answer scores full marks (unless from obvious incorrect working) Answer: 7 | A1 |

|---|---|
| e.g. 1 – 0.15 (= 0.85) or 100(%) – 15(%) (= 85(%)) | M1 |
| e.g. 39 865 ÷ 0.85 or 39 865 ÷ 85 × 100 oe | M1 |
