Refer to the given data. If the prices of labor and capital are $9 and $15, respectively, and labor and capital are the only inputs, the firm's economic profits will be
a. $82.
b. $67.
c. $102.
d. $28.
Correct Answer:
C
Working note:
5 unit of labor and 3 units of capital will be deployed on the basis of MRP = price as the optimum condition to select the quantity of input.
Economic profit = Profit from the deployment of labor + profit from the deployment of capital
Economic profit = (45+36+27+18+9 - 5*9) + (24+18+15 - 3*15)
Economic profit = $102
