Suppose that a firm has a budget of $30,000, that the wage rate is $10 per hour, and that the rental rate is about $100 per hour. I f the wage rate increases to $15 per hour and the rental rate of capital rises to $120 per hour, what happens to the producer budget or cost line? What will happen to the equilibrium of level output because of this change in factor prices? What will happen to the relative usage of labor and capital because of the change in factor prices? Explain.
