For supply curve, at a price of $12, one seller will be willing to sell; at a price of $16, two sellers will be willing to sell; and so on, until, at a price of $30, all five sellers would be willing to sell. The opposite will apply to the behavior of buye rs whereby at a price of $29; one buyer will be willing to buy and at a price of $10; all five buyers would buy. The market equilibrium is at a price of $3 because the quantity supplied equals the quantity demanded which is 20 widgets at this price.
