Need help with these questions thanks.

Question 1 If a retail clothing shop has to pay monthly rental of A$10,000 and has variable costs of A$20,000 for 200 units of sales per month, what minimum price must it sell its goods in the market in the short-run and the long-run for the shop to continue operating? Question 2 a) A prot-maximizing business incurs an economic loss of $10,000 per year. Its xed cost is $15,000 per year. Should it produce or shut down in the short run? Should it stay in the industry or exit in the long run? b) Suppose instead that this business has a xed cost of $6,000 per year. Should it produce or shut down in the short run? Should it stay in the industry or exit in the long run
