I need some help with this review

(35p) A rm sells its product in a perfectly competitive market where other rms sell an identical product at a price of $120 per unit. The rm's total cost is C(q) = 2500 + (12. (a) (b) How much output should the rm produce in the short-run? If all the other competitors in the market have the same cost function, what would you expect to happen to the price of the output in the long-run? Explain your answer clearly and, if you believe the current output price is not stable in the long-run, determine the long-run equilibrium price. Assume now that the current market price for the output is $100 per unit, and the government decides to tax producers at a rate of $5 per unit of output produced. What will be the short-run consequence of this taxation? What is likely to happen in the long-run if the tax is maintained
