q=KL,now assume that capital is fixed at K=K^0
a)Find the conditional (short run)demand for labor
b)find the short run total cost function
c)also find the short run cost functions:fixed cost,variable cost,marginal cost,average fixed cost,average variable cost and average total cost.
d)sketch the cost curves.In one graph put in short run total cost,variable cost,and fixed cost curves and in the other,the short run marginal cost,average total cost,average variable cost,and average fixed cost.
