Answer: the market price will decrease but the number of firms will increase.
Explanation:
A monopoly exists when there is one supplier of a particular good or service in the market. A monopolistic firm has full control of the market, and therefore sets the price and the supply of a good or service. Typically a monopoly usually selects a higher price and also lesser quantity of output to be supplied. There is also a high barrier to entry.
When the government dissolves the monopolist, and the market becomes competitive, this will lead to more firms coming into the market. As a result of more firms coming to the market, there'll be cheaper price of goods. The market price which is determined by the forces of demand and supply will decrease.
