find the marginal cost of q:

rm has a Cobb-Douglas production function, q=2L0.50K0.50 it faces factor prices of W=20 and r=50, and its capital is fixed at K=100, what are its short-run verage fixed cost (AFC), average variable cost (AVC), and marginal cost (MC) functions? Plot lese curves. he firm's average fixed cost, as a function of q, is AFC=q5000. The firm's short-run average variable cost, as a function of q, is AVC= Cost per unit, \$ Q Q q, Quantity
