# C20 · After-own staff

## Complete neutral brief

For a fictional community display, need exactly 36 items. Pretend A packs 6 for $12; B packs 9 for $18. One $7 fee, budget $80. Whole packs/no extras. Choose lower cost among valid plans; if tied choose fewer packs. Send a useful note.

## Specific criterion

Choose a valid whole-pack plan, model its cost and budget check, and communicate assumptions and a useful decision.

## One staff worked possibility

A:6 packs/$79, $1 left. B:4 packs/$79, $1 left. Both supply 36; choose B. State quantity and fee assumptions.

## Neutral support limit

Ask one neutral 'What does that amount count?' question if necessary and record it. Teach afterwards rather than covertly supplying the model.

## Evidence scope

An individual response in a selected mode. Read/scribe if needed and record support; hide the teacher model first. Formative partial evidence, not an annual grade.
