We need to convert the 800,000 Japanese yen Carlos paid to Mexican pesos using the exchange rates in the table. 
The exchange rate on August 1, 2016, for Japanese yen was 102.62 yen per dollar. So, 800,000 yen is equal to 800,000/102.62 = 7,794.896 dollars. 
The exchange rate on August 1, 2016, for Mexican pesos was 18.396 pesos per dollar. So, 7,794.896 dollars is equal to 7,794.896 x 18.396 = 143,428.5744 pesos. 
Therefore, the iPhone case cost Carlos approximately 146,396 pesos (rounded to the nearest peso).
