Foundation June 2019 Paper 2 Q11
11 \(P = 7r + 3q\)
Work out the value of \(P\) when \(r = 5\) and \(q = -4\) (2)
| Answer | Mark | Mark scheme |
|---|---|---|
| 23 | M1 | for substitution eg. \(7 \times 5\) and \(3 \times -4\) or \(7(5) + 3(-4)\) |
| A1 | cao |
Additional guidance
\(7 \times 5\ (= 35)\) and \(3 \times -4\ (= -12)\) may be seen separately but both must be seen for the award of M1
