Consider a market where demand is D=1606P. An individual firm in this market can supply quantity QS=P2 in the short run, for any price above

Suppose that long-run firm-level supply in this market is the same as short-run supply, however the long run allows more firms to enter (and existing firms to potentially exit). Assuming that there are no barriers to entry (or exit) , find how many firms will be in the market in the long run competitive equilibrium.
