Suppose That the Perfectly Competitive Soybean Industry in the United

Suppose that the perfectly competitive soybean industry in the United States is monopolized. Under perfect competition, the equilibrium price was $2 and quantity was 100,000. The monopolist raises price to $5 and restricts quantity to 70,000. Assume that the monopolist is maximizing profits and that the monopolist faces a linear, upward-sloping marginal cost curve that begins at the origin. Also assume that this marginal cost curve is the industry supply curve under perfect competition. What is the loss in consumer surplus that corresponds to dead-weight loss?

A) $210,000
B) $200,000
C) $90,000
D) $45,000
