Growth & Decay | OCR GCSE Higher Maths | 40 Worked Examples (J560)

40 fully worked OCR GCSE (9-1) Higher growth and decay questions (spec J560, content OCR 5.03), graded Easy to Challenging. Every solution is broken down one step at a time with a plain-English reason for each line and OCR-style M/A/B mark-scheme annotations in the right margin, including the cascades and ‘or equivalent’ / ‘seen or implied’ guidance OCR uses on multi-step questions. Covers growth and decay multipliers, compound interest, depreciation, population growth and radioactive-style decay, forming and using A = P x M^n, completing growth and decay tables, interpreting a given model V = P x k^n (rate, initial value, prediction), finding the number of complete years by trial (no logs, as required at GCSE), combining several changes into a single multiplier, comparing simple (linear) with compound (exponential) growth, and finding an unknown rate by taking a root. Written for OCR’s no-formula-sheet rule, so the pack opens with the key facts students must memorise. Ideal for revision, homework, and cover lessons.
