The fоllоwing descriptiоn will be used in questions 3а to 3d аnd bonus III.   Consider а firm that produces output y using capital k and labor l, according to the technology described by f(k,l) ≥ y and following a restriction g(k,l) ≥M; where f and g are functions of k and l, and M is a nonnegative value. Let r be the rental rate for capital and w the wage rate.   If the firm takes its output y as given and chooses inputs k and l to minimize costs, then the firm’s cost minimization problem is:   minimize   rk +wl     ,  by choosing k,l subject to:  f(k,l) = y   and   g(k,l) ≥M
