What’s inside:
Easy: direct proportion, finding and using the constant of proportionality, and the unitary method.
Medium: inverse proportion, proportion to a square or cube, and forming the equation y = k x^n.
Hard: mixed direct-and-inverse relationships, proportion in worded and graphical contexts, and multi-step problem solving.

Every solution forms the proportionality equation explicitly, keeps one step per line with an annotation on each, and places B, M and A marks where the mark scheme awards them.
