Answer:
reduce output
Step-by-step explanation:
The marginal cost ($26) is greater than the marginal revenue ($25). In order to maximise profit, marginal cost should he reduced up to the point where marginal cost equals marginal benefit.
A firm should shutdown, reduce production to zero if average variable cost is greater than price but in this question, the firm shouldn't shut down since price ($25) is greater than average variable cost ($24).
