What will happen to price after the imposition of heavy tax in a monopoly?

In a monopoly, the imposition of a heavy tax typically leads to an increase in production costs for the monopolist. To maintain profitability, the monopolist is likely to raise prices for consumers, as they have market power to do so without losing all their customers. This price increase can result in reduced consumer surplus and potential decreases in overall quantity demanded, depending on the price elasticity of demand for the product. Ultimately, the burden of the tax is often passed on to consumers through higher prices.
