Answer:
I would encourage the proprietor to promptly close down his firm. On the off chance that he closes his firm down, he will make lesser misfortunes than if he works his firm. On the off chance that the normal variable expense is higher than the harmony value, at that point in the event that he closes down, his misfortune will be the fixed expense and on the off chance that he works, his misfortune would be fixed cost+ (avc-value) x amount. Consequently, it is better not to work, even in the short run.
