13. mRS=MPx1/MPx2=X2/X1
At optimality MRS=P1/P2
Thus MRS=X2/X1=17/11 —————(1)
Expenditure on X1=P1X1=17X1=561
X1=561/17=33
put in (1)
Then X2=33*17/11=3*17=51
Expenditure on X2=51*11=561
ans is D

A firm uses two inputs x1 and x2 to produce output y. The production function is given by f(x1, x2) = p min{2x1, x2}. The price of input 1 is 1 and the price of input 2 is 2. The price of output is 10. 4. A firm uses two inputs 21 and 22 to produce output y. The production function is given by f(x1, x2) = V min{2x1, x2}. The price of input 1 is 1 and the price...
cardboard boxes are produced in a perfectly competitive market. each identical firm has a short run total cost curve of TC= 3Q^3 - 12Q^2 +16Q + 100, where Q is measured in thousands of boxes per week. calculate the output for the price below which a firm in the market will not produce any output in the short run. ( i.e., the output for the shut down price) a 2^1/2 b. 2 c. 1/2 d. 1/square root of 2 2)...
NEED ALL ANSWERS PLEASE Problem 3 [24 marks] A competitive firm uses two inputs, capital (k) and labour (), to produce one output, (y). The price of capital, W, is S1 per unit and the price of labor, wi, is SI per unit. The firm operates in competitive markets for outputs and inputs, so takes the prices as given. The production function is f(k,l) 3k025/025. The maximum amount of output produced for a givern amount of inputs is y(k, l)...
NEED ANSWERS OF PART (f,g,h,j) Problem 2 [21 marks] Consider a firm that uses two inputs. The quantity used of input 1 is denoted by x, and the quantity used of input 2 is denoted by x2. The firm produces and sells one good using the production function f(x1, x2)-4x053x25. The final good is sold at price P $10. The prices of inputs 1 and 2 are w$2 and w2 $3, respectively. The markets for the final good and both...
