Need help with the letter (b) of this exercise:

1 0.7 Suppose the total-cost function for a rm is given by C=q(v+2M+w). 3.. Use Shepherd's lemma to compute the (constant output) demand function for each input, k and l. b. Use the results from part (a) to compute the underlying production function for q. c. You can check the result by using results from Example 10.2 to show that the CBS cost function with o = 0.5, p = 71 generates this total-cost function. \f\f
