Cost of electricity

I have been renting the same condo for years, but for 2023 I have been asked to pay 50 USD more per night to run the AC in one bedroom. Is this reasonable?

US$50 or MXN$50? Fifty U.S. dollars or fifty Mexican pesos. Fifty pesos is reasonable. Fifty U.S. dollars is outrageous. Note that the $ is also used for pesos.

Point of information: Most reliable accounts state the $ was used for pesos before it was used for dollars. There are various histories of the origins of the use. Some say that when the U.S. adopted the $, it actually had two vertical lines through the S to differentiate it from the peso symbol. The $ with two vertical lines is far less common now.
