Answer: reduce output.
Step-by-step explanation:
In a competitive market, firms do not have control over the price that they sell their goods in the market but they do have control over their costs. It is recommended to produce/ sell goods at a quantity where Marginal Revenue will equal Marginal cost (MR = MC).
In a Competitive Market, Price is the same as Marginal revenue which means that Marginal revenue here is $25 and the Marginal Cost is $26. At this quantity of output, the Marginal Cost is larger than the Marginal revenue.
Company should therefore reduce output to a quantity where Marginal Cost will equal Marginal revenue.
