Y10 Core Booklet 14 - Ratio, interest and graphs | Original 29-page PDF

Download Dr Taylan Çeltik’s original 29-page Y10 Core Booklet 14 - Ratio, interest and graphs, covering ratio sharing, simple and compound interest, direct and reverse percentages, substitution, calculator tables and quadratic/reciprocal graphs.

This is the original teaching booklet, retaining its historical question numbers, diagrams, equations and included selected worked examples. It is not a newly authored complete solutions pack. Digital PDF download only.

A separate clarification PDF is included. Page 15, Q14-16: the scanned first three x-values and lower domain limit have faint or missing minus signs. Read the table as x = −3, −2, −1, 0, 1, 2, 3 and use −3 ≤ x ≤ 3, consistently with the plotted graph on page 16. The function is y = x² + x.

Historical scanned worked examples are softer than the typed text. All page content remains in its original positions. Some minus signs on page 15 are faint or missing in the original scan; the clarification identifies the intended domain from the matching graph.

Use the exact question/page references in each matching video description. The booklet includes further practice beyond each selected recording. Spiral learning connects these skills with earlier number, algebra, graph and geometry ideas.
