Suppose demand for automobiles in the United States is given by: P= 100−0.09QD where P is the price for new vehicles in dollars and QD is the quantity demanded per month. Assume the supply of automobiles is given by P= 4 + 0.03QS where again P is the price in thousands of dollars and QS is the quantity sold per month in hundreds of thousands. a.) Solve for the market equilibrium price and quantity. b.) Depict this market graphically, and...

Suppose that you have been hired to analyze wages in a simple market. The demand for labour and supply of labour can be represented by the following equations, where L stands for the quantity of labour (measured in thousands of workers) and W stands for the wage rate (measured in dollars per hour): Demand: Supply: P = 100 - 5W S = 5W a. Calculate the equilibrium wage (price) and quantity of labour employed in this market. b. A new...
