I need help on this macroeconomic question

2. \"Traveling in Mexico is much cheaper now than it was ten years ago,\" says a friend. \"Ten years ago, a dollar bought 10 pesos; now a dollar buys 15 pesos.\" Is your friend right or wrong? Inflation over the ten-year period was 25% in the US and 100% in Mexico, has it become more or less expensive to travel in Mexico? Use a concrete example, such as an American hot dog versus a Mexican taco to convince your friend
