In Problem 19 in Chapter 8 you derived Hannah and Sam's long-run and short-run cost function when they have the Cobb-Douglas production function Q = F( L, K) = 10L0.25K0.25, both a worker and a unit of capital cost $1,000 per week, and they initially remodel 100 square feet a week. Their capital is fixed in the short run but variable in the long run. What are their long-run and short-run supply functions? Graph them.
