Suppose SunEdge Corp., a solar panel manufacturing company, has the following production function: where q represents the number of solar panels produced, K is the amount of capital (e.g. factory equipment, machinery), and L is the amount of labor (e.g., worker hours). If wages are $15 per hour and the rental rate for capital is $25 per hour, derive SunEdge’s long-run cost curves — total cost, variable cost, fixed cost, average total cost, average variable cost, and average fixed cost.
