Final answer:
The provided information on Mexican peso exchange rates does not specify Procter & Gamble's pricing method for keeping product prices low. The discussion focuses on the factors affecting exchange rates rather than specific pricing strategies.
Step-by-step explanation:
The method of pricing that Procter & Gamble uses to keep prices below 11 or 12 pesos, in light of the fact that Mexican customers usually carry small coins, is not specified in the provided figures and information about the Mexican peso exchange rates. The figures and discussion provided relate to how factors such as expectations about future exchange rates and inflation can affect the demand and supply for the Mexican peso in the foreign exchange market, which in turn affects the equilibrium exchange rate. These factors are crucial for multinational companies like Procter & Gamble to consider when setting prices for their products in international markets. However, the pricing strategy used to keep prices within a certain range may involve market segmentation, psychological pricing, or cost-based pricing, none of which are specifically addressed in the provided material.
