Explanation:
Any monopoly is able to set the price of the product or service it offers at whatever level it desires.
That doesn't mean that Amanda's profit will increase if she decides to increase the price of the service she provides, since customers are free to decide if they want to pay for that service or not. No one can be forced to buy a product or service, as customers we can decide not to use that service if we consider that the price is too high.
