## Core claim Increasing price from $3.50 to $4.39 gives up $243 of weekly revenue but adds $243 of weekly gross profit.
## Evidence Fitted linear demand Q = 2097.0 + (-300.0)P (R² = 1.00, n = 9).
## Next move Test $4.24 to $4.54 next.
## Caveats - The engine assumes a linear demand response inside the chosen price range. - Fixed costs are not modeled here; this is a gross-profit optimization rather than full EBITDA. - Use recent market context before moving outside the observed price band.
