| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
| 146 with correct working | 5 | M2 for \(3x + 36 = 180\) oe or M1 for \((x - 14) + (2x + 50) = 180\) oe AND A1 for [\(x =\)] 48 M1 for \(2 \times\) their \(x + 50\) If 0 or 1 scored, instead award SC2 for 146 with no or insufficient working If 0 scored, instead award SC1 for [\(x =\)] 48 or \(y = 2x + 50\) | “Correct working” requires evidence of at least M2 or M1M1 Trials: Correct answer from trials scores 5 Allow correct substitution into \((x - 14) + (2x + 50)\) to imply M1 if 180 also stated Dep on at least M1 their \(x \lt 65\) SC marks may be seen on diagram |
