5. COST CURVES (10 POINTS) (a) (5 POINTS) You are operating a widget factory, and the short-run total cost function for pro- ducing y widgets, denoted TC (y), is TC (y) = 10y' + 20y + 200 Calculate the following cost curves: average variable cost (AVC (y)); average fixed cost (AFC (y)); average total cost (ATC (y) ); and marginal cost (MC (y)). (b) (5 POINTS) You are operating a widget factory, and the production function for producing y widgets is y = 5x1 + 5x2 The factor price of x1 is w1 = 2, and the factor price of x2 is w2 = 4. There are no fixed costs. Calculate the average total cost (ATC (y)) curve and marginal cost (MC (y) ) curve
