The Solo Coal Mine is the only employer in the small town of Way out there. The market supply of coal miners is Qs = 0.02W - 200, where W is the annual wage of a coal miner and Q is the number of people who would accept employment as a coal miner. What is the coal mine's marginal expenditure function?
A. ME = 50Q + 10,000 B. ME = 100Q + 10,000 C. ME = 200Q + 500 D. ME = 250Q + 500
