Consider a perfectly competitive market described by the supply function P = 10 + 0.3Q and demand function P = 60 - 0.2Q. Suppose the market is initially in equilibrium. If the government intervenes in the market and imposes a price restriction of P = $25 per unit, the impact on the market rounded to the nearest whole unit will be a:
surplus of 50 units
surplus of 125 units
shortage of 125 units
shortage of 175 units
