Use the tangency rule to determine the cost-minimizing bundles of labor and capital for a general Cobb-Douglas production function, q = ALakb, and for the specific beer production function, q = 1.516L 0.6K0.4 where w = $120 and r = $16. Determine the tangency condition for the general Cobb-Douglas production function. At the cost-minimizing bundle as a function of L, a, b, w, and r, wb K= ra L . (Properly format your expression using the tools in the palette. Hover over tools to see keyboard shortcuts. E.g., a fraction can be created with the / character.) Substitute in the specific values for our beer example. At the cost-minimizing bundle as a function of L, K =
