uestion 3 (1 point) the production function is f(x1, x2) = x1/21x1/22. If the price of factor 1 is $10 and the price of factor 2 is $20, in what proportions should the firm use factors 1 and 2 if it wants to maximize profits? Question 3 options: We can’t tell without knowing the price of output. x1 = 2x2. x1 = 0.50x2. x1 = x2. x1 = 20x2. Question 4 (1 point) A firm has the production function f(X,...

1. A buyer has Cobb-Douglas preferences such that mrs = − x2/ x1 . He starts with 3 units of good 1 and $50. Use this information to answer the following questions. (a) Find an expression for this consumer’s net demand for good 1 (i.e. how many more units he will buy given price p). (b) Sketch this demand curve. (Make sure you label the axes and put p on the vertical axis.)
