Let's analyze the problem step-by-step given the exchange rate table:
1. Reference Currency Identification:
The table's format indicates that all exchange rates are given as per one unit of the euro. This suggests that the reference currency used in the table is the euro.
2. Finding the Exchange Rate of the Euro to Swiss Francs:
From the table, we can find the exchange rate of the euro to Swiss francs. According to the chart, one euro would buy 1.2149 Swiss francs.
3. Finding the Exchange Rate of the Euro to US Dollars:
Similarly, we can determine the exchange rate of the euro to US dollars from the table. It shows that it would cost 1.2839 US dollars to buy one euro.
Summarizing:
- Reference Currency: euro
- One Euro Buys Swiss Francs: 1.2149 Swiss francs
- Cost in US Dollars to Buy One Euro: 1.2839 US dollars
Therefore, completing the problem:
- The reference currency is the euro.
- One euro would buy 1.2149 Swiss francs.
- It would cost 1.2839 US dollars to buy one euro.
