Foundation November 2019 Paper 2 Q11
11 \(c = 250 - 16^2\)
\(d = \dfrac{18 \times 14}{-28}\)
Work out the value of \(\; c \times d\) [2 marks]
| Answer | Mark | Comments |
|---|---|---|
| 54 | B2 | B1 \((c =) -6\) or \((d =) -9\) or \((cd =) -\dfrac{1512}{-28}\) oe fraction or \((cd =) \dfrac{1512}{28}\) oe fraction |
Additional guidance
| Answer 54 with any or no working | B2 |
| \((c =) -6\) or \((d =) -9\) seen even if not subsequently used | B1 |
| \((c =) -6\) or \((d =) -9\) may be seen by the given calculations | B1 |
| \(250 - 16^2 \times -9 = 2554\) | B1 |
| \(250 - 16^2 \times \dfrac{18 \times 14}{-28} = 2554\) | B0 |
| Answer 2554 with no working | B0 |
