Demand Curve: To determine the demand curve, we must first determine the pricing for each unit of quantity. This can be accomplished by multiplying the total revenue values by the quantity. The following are the price ranges:

If the monopolist firm of Exercise 3 was a public sector firm. The government set a rule for its manager to accept the government fixed price as given (i.e. to be a price taker and therefore behave as a firm in a perfectly competitive market). And the government has decided to set the price so that demand and supply in the market are equal. What would be the equilibrium price, quantity and profit in this case?
