| Difficulty | Moderate -0.8 This is a straightforward algebraic rearrangement requiring cross-multiplication and collecting terms with C on one side. It's a routine C1 manipulation exercise with no conceptual difficulty, easier than average A-level questions but not trivial since it requires multiple steps and careful handling of the variable appearing twice. |
| Spec | 1.02k Simplify rational expressions: factorising, cancelling, algebraic division |
Make $C$ the subject of the formula $P = \frac{C}{C + 4}$. [4]
