Answer #1

8.

The slope of the isoquant is changed in capital upon the change in labor equals MPL divided by MPK

the correct option is c

9.

when (MPL/MPK) > (w/r) means labor is expensive so the firm would employ more capital.

the correct option is a

10.

marginal revenue product equals marginal product multiplied by marginal revenue which altogether equals price. So the ratio of the price of variable input divided by marginal product will be equal to marginal revenue.

the correct option is c

11.

False. It is the product of price and the marginal product of labor which equals the price of the product.

12.

The firm if the price is less than the average total cost would remain operating if the price is greater than the average variable cost in the short run but it will shut down in the long run.

the correct option is D
