1.Draw the average cost (AC), marginal cost (MC) and variable cost (VC) in short-run curves. Explain if AC curve is increasing, MC curve? Explain if AC curve is decreasing, MC curve? Explain if AC is minimum, MC curve? 2.What is meaning of shape the average cost curves in short-run production function? Given the wage rate is RM20 per unit of labor, short run production function is q = 20L, the average variable cost (AVC) equals?
