Final answer:
The implied purchasing power parity (PPP) of the peso per dollar is approximately 8.50 pesos per dollar.
Step-by-step explanation:
The implied purchasing power parity (PPP) of the peso per dollar can be calculated by dividing the price of a Big Mac in Mexico (in pesos) by the price of a Big Mac in the U.S. (in dollars). In this case, the price of a Big Mac in Mexico is 29.0 pesos and the price in the U.S. is $3.41. So, the implied PPP is 29.0 pesos divided by $3.41, which equals approximately 8.50 pesos per dollar.
