9 observations fit a linear demand curve with R²=1.00. Moving from the revenue-max price to the profit-max price gives up $243 of revenue and adds $243 of gross profit.
Each observed point sits against the fitted demand line. Drag the live model below and the selected price dot follows the same curve.
The server fits once. The artifact carries the rest of the interaction in plain client-side JavaScript.
