The table below presents the average monthly demand and supply of $4^{\text{'}}{8}^{\text{'}}$ sheets of plywood from a typical home building supply store.

Imagine Florida passes a "price gouging" law that prevents home building supply stores from raising the price of plywood when hurricanes threaten.
