To complete the table, we can use the supply function Qs = -300 + 20P to calculate the quantity supplied (Qs) for each point on the table. For example, at point B, the price is 18 and the quantity supplied is Qs = -300 + 20(18) = -240. Similarly, at point C, the quantity supplied is Qs = -300 + 20(10) = -200, and at point E, the quantity supplied is Qs = -300 + 20(25) = -80.
