2. Tive has a crafts store that makes jewelry using beads (B) and copper (O). Her production function for jewelry is given by Suppose she can buy beads and copper at prices Py and Po, respectively. (a) Calculate Tive's marginal rate of technical substitution between B and C. (b) Does this production function have increasing, constant, or decreasing returns to scale? Explain.(c) Set up the cost minimization problem you would use to calculate Tiva's cost function O(Q) in Lagrangian form. (Note: You do not need to solve it or derive first order conditions. Suppose Tive decides to branch out in her jewelry offerings by getting a 3D printer. The cost of producing new 3D printed jewelry is C(Q) = 25 + For the rest of this problem, assume Tive can produce fractions of jewelry, don't worry about restricting your answers to whole numbers. (d) Compute Tive's marginal cost and average cost of production for 3d printed jewelry. (e) Explain why she will shut down when the market price falls below P = 5
