Use the tangency rule to determine the cost-minimizing bundles of labor and capital for a general Cobb-Douglas production function, q = AL akb and for the specific beer production function, q = 1.516L 0.610.4 where w = $24 and r = $32. 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, K=.
