|---|---|---|---|
| 50 with correct working | 4 | B2 for 2400 or M1 for \(\frac{15}{100} \times 16000\) oe M1 for (17400 – their 2400) ÷ 300 oe If 0 or M1 scored, instead award SC2 for answer 50 with no or insufficient working If 0 scored, instead award SC1 for 15 000 with no or insufficient working | “Correct working” requires evidence of at least B2 or M1M1 or alternate convincing approach For M1 not 15% × 16000 alone Allow repeated addition of 300 need 5 additions, condone 1 error. Could e.g. start 2400 and try to add on to make 17400 Candidates who use 17400 throughout treat as MR (see marking instructions) B2 for 2610 (15%) and answer 49.3 condone rounded to 49 or 50 if multiples of 300 are used instead of division |
