If the exchange rate for Mexican pesos has changed from 10 pesos to 9 pesos per dollar?

If the exchange rate for Mexican pesos has changed from 10 pesos to 9 pesos per dollar, it indicates that the peso has appreciated relative to the dollar. This means that it now takes fewer pesos to purchase one dollar, suggesting a stronger peso. As a result, imports from the U.S. may become cheaper for Mexican consumers, while Mexican exports to the U.S. might become more expensive for American buyers.
