Suppose the monopoly has marginal costs MC = 2q and faces the demand curve p= 90 - q. A politician suggests to impose a per-unit tax of $1 on the monopolist. Calculate the monopoly price, output, profit, and deadweight loss in the absence and presence of the tax. Represent the problem graphically. What is your conclusion?

thank you so much James! I really appreciate your help. Could you please help me figure out how to calculate the deadweight loss if you know how to. Thank you again
