17 DISCUSSION QUESTION The demand for electric power in Sol Province is p = q, where p and q represent the price in thousands of dollars and quantity in Megawatt hours, respectively. Suppose that an electricity plant generates power at a constant marginal cost of $1000 per megawatt hour up to a capacity of 10 megawatt hours. Sol Province requires the plant to implement marginal-cost pricing.

18 DISCUSSION QUESTION Illustrate the price and quantity with marginal cost pricing. Suppose that demand grows to P=20-0.1q. At a price of $1000 per megawatt hour, what is the minimum number of plants needed to produce the quantity demanded?
