Answer:
The firms make a $1 per bushel in profit.
Step-by-step explanation:
When the price is greater than the long run total costs, then a profit is being generated. This helps the firms in the perfectly competitive oat industry to remain in the industry since they are making 100% profit on their investments, which they may not get elsewhere. If they are not making such large profits, some of the firms may decided to leave the industry and relocate their resources to other industries where they can make enough profits.
