Marginal cost for the dominant firm is $0.75 per gallon. QM = 140,000 - 32,000P QF = 60,000 + 8,000P, where QM = market quantity demanded, and QF = supply of competitive fringe. Quantities are measured in gallons per week, and price is measured as a price per gallon. The price that would prevail in the market under the conditions described above is a) 1.572 per gallon b) 1.754 per gallon c) 1.271 per gallon c) 1.375 per gallon
