The exchange rate between Mexican pesos (MXN) and US dollars (USD) fluctuates constantly due to market conditions. As of my last update in January 2022, the exchange rate was approximately 1 USD to 20 Mexican pesos.
Using this exchange rate, 500 Mexican pesos would be roughly equivalent to 25 US dollars.
However, please note that exchange rates can vary based on factors such as economic conditions and geopolitical events. For the most accurate and up-to-date exchange rate, it's best to check with a reliable financial source or currency converter.
