3. Duane breeds parrots for a living. He has discovered that the production function for parrot chicks (Q) is: Q=K0.5 p0.5 where K is capital (for example nest boxes, cages and the like) and F is parrot food. The price of K is 88 and the price of F is 82. (a) What type of production function is this? Explain. (b) Does this production function exhibit constant, increasing or decreasing returns to scale? Provide a graph of the function using Excel. (c) Find the marginal products of capital and food. (d) Suppose that Duane wants 144 parrot chicks, how much K and F should be employed to minimise costs. What is the cost of producing 144 parrot chicks? 1

Prunella raises peaches where L is the number of units of labor she uses and T is the number of units of land she uses. Her output is f(L,T) = LT bushels of peaches. Currently, the cost of land is 8, the wage for labor is 9, and the price of peaches is 10. Prunella is currently maximizing her profits. Which occurences would cause the quantity of labor used to decrease? O An increase in the price of peaches O A increase in the price of labor O An increase in the Marginal Product of Labor O All of the above
