Question 4 (Cost Curve) A firm's production function for pretzels is shown in the figure below. If the firm's fixed cost equals $200 per time period and the wage rate equals $1 per unit of labor per time period, calculate the firm's average fixed cost (AFC), average variable cost (AVC), average cost (AC) and marginal cost (MC) schedules (hint: you should draw a table that contains all those costs). Do these cost functions follow the general rules concerning the relationships between MC and AVC?
