To analyze the situation, we need to look at the exchange rates provided:
-
Yesterday, 100 U.S. dollars (USD) traded for 150 Canadian dollars (CAD). This implies the exchange rate was: \[ \text{Exchange Rate (USD to CAD)} = \frac{150 \text{ CAD}}{100 \text{ USD}} = 1.5 \text{ CAD/USD} \]
-
Today, 150 U.S. dollars traded for 300 Canadian dollars. This gives us the new exchange rate: \[ \text{Exchange Rate (USD to CAD)} = \frac{300 \text{ CAD}}{150 \text{ USD}} = 2 \text{ CAD/USD} \]
Now, let's determine what has happened to the U.S. dollar with respect to the Canadian dollar:
- Yesterday's rate was 1.5 CAD per 1 USD, and today it is 2 CAD per 1 USD.
- Since it now takes more Canadian dollars to buy 1 U.S. dollar (2 CAD compared to 1.5 CAD), the U.S. dollar has appreciated relative to the Canadian dollar.
- Conversely, this means the Canadian dollar has depreciated against the U.S. dollar, as it is now weaker in terms of USD.
Given this analysis, the correct response is:
The U.S. dollar appreciated with respect to the Canadian dollar, and the Canadian dollar depreciated with respect to the U.S. dollar.
