# How would I solve for long run average profit?

I was looking at a problem, and I was wondering how I would set this up. Any help would be welcome. Thank you!

A store stocks a particular item. The demand for the product each day is 1 item with probability 1/6, 2 items with probability 3/6, and 3 items with probability 2/6. Assume that the daily demands are independent and identically distributed. The store uses an (s, S) = (2, 4) policy to manage its inventory: each evening if the remaining stock is less than or equal to s items, the store orders enough to bring the total stock up to S items next morning. These items reach the store before the beginning of the following day. Assume that any demand is lost when the item is out of stock. Assume that each item sells at $150, the variable cost per item is cv =$50, the fixed cost for each order is cf = $100, and the holding cost is$5 for each item held overnight. Find the long-run average profit per day
