Answer:
Jenny will stay in the short and long run and Joe will stay in the short run and exit in the long run.
Step-by-step explanation:
Joe's price is > average variable cost but < than average total cost. This means that he can continue to operate in the short run as long a the AVC is lower than the price, but on the long run he will close. He will not be able to make a profit in the long run, but his business can "survive" in the short run.
Jenny's price is > average variable cost and > than average total cost. She can continue to operate in the short and long run.
