Answer to Question 1

No. A perfectly competitive firm should keep investing in capital up to the point where the expected rate of return is equal to the interest rate. In this case, the interest rate is higher. This implies that the opportunity cost of the funds used to purchase the equipment is greater than the expected revenues from the equipment. Thus, it was a bad decision.

Answer to Question 2

If the firm decides to produce the 36th unit of output, its average variable cost will rise because the marginal cost is greater than the average variable cost.
