Foundation November 2021 Unit 2 Q12
12. A company produces 440 boxes of paper clips each day.
Each box contains between 320 and 330 paper clips.
Calculate the approximate total number of paper clips produced in 200 days.
Give your answer to the nearest ten million.
You must show all your working. [4]
| Scheme | Marks | Comments |
|---|---|---|
| (Total number of paper clips =) 200 × 440 × n where 320 ≤ n ≤ 330. | M2 | M1 for 200 × n OR 440 × n where 320 ≤ n ≤ 330. Allow use of 400 or 450 for 440. Note If n taken to be 225 or 425 treat as a misread and allow M2 but penalise −1 from any further A1, B1 marks gained. |
| Correct evaluation. | A1 | CAO from their numbers if M2 gained. (n=320 gives 28 160 000, n=325 gives 28 600 000, n=330 gives 29 040 000.) |
| (To the nearest ten million) 30 000 000 (paper clips) | B1 | FT ‘their evaluation’ if greater than 5 million. A final answer of 30 million implies M2A1B1. Allow M2A0B0 for an unsupported final answer of 28 000 000 or 29 000 000. |
