Foundation November 2022 Paper 2 Q8
8 Work out the value of \(\quad 3r + 4t \quad\) when \(\quad r = 13\) and \(t = -2\) [2 marks]
| Answer | Mark | Comments |
|---|---|---|
| \(3 \times 13 + 4 \times -2\) or \((3r =)\ 39\) or \((4t =)\ {-8}\) | M1 | oe |
| 31 | A1 |
Additional guidance
| \(39 + 8\) | M1A0 |
| 39 or −8 may be implied by a calculation eg \(3 \times 13 + 4 \times 2 = 47\) | M1A0 |
| 47 only does not imply 39 | M0A0 |
| Values are not implied by incorrect expressions eg only \(39r\) | M0 |
| Incorrect further work | A0 |
