Answer: In the short run, Delores should leave output unchanged; in the long run, she may need to consider exiting the market.
Step-by-step explanation:
The annual fee for the food preparation license that Delores operates under is to be considered a fixed cost. Now the thing about Fixed costs is that they don't change regardless of output. You could produce 59 bags and pay $20 for power or you could produce 10 bags and still pay the $20.
For this reason therefore, Delores should not change output in the short run because she will still have to pay for the annual fee.
In the long run though, if the situation persists, she should consider leaving the business/market because she will be making losses.
