Answer: continue to operate even though she is taking an economic loss.
Step-by-step explanation:
Since at Zoe's optimal level of production in the short run, the price is more than the average total cost and P > AVC, then she should continue to operate even though she is taking an economic loss.
This is because even though she's making loss as the price is less than the average total cost, since the price is greater than the average variable cost, then she should continue in operation. Assuming P < AVC, then the company should shutdown in this case as only th fixed cost is incurred.
