Let's carefully analyze the exchange rate table provided:
[tex]\[
\begin{array}{|c|c|}
\hline
\text{Currency} & \text{\begin{tabular}{c}
Exchange Rate \\
April 3, 2013 \\
(Euro = 1)
\end{tabular}} \\
\hline
\text{Bulgarian lev} & 1.96 \\
\hline
\text{Canadian dollar} & 1.301 \\
\hline
\text{Swiss franc} & 1.2149 \\
\hline
\text{British pound} & 0.8482 \\
\hline
\text{Japanese yen} & 119.4065 \\
\hline
\text{US dollar} & 1.2839 \\
\hline
\end{array}
\][/tex]
The header of the table mentions "Exchange Rate \n April 3, 2013 \n (Euro = 1)". This statement indicates that the values listed in the table are the exchange rates of various currencies relative to 1 Euro.
- For example, for the Bulgarian lev, the exchange rate is 1.96, which means 1 Euro is equivalent to 1.96 Bulgarian lev.
- Similarly, the exchange rate for the Canadian dollar is 1.301, which indicates 1 Euro is equivalent to 1.301 Canadian dollars.
- The same interpretation applies to all other currencies listed in the table.
Thus, the reference currency indicated by this table is the Euro. All listed exchange rates define the value of one unit of Euro in terms of different foreign currencies.
Therefore, the reference currency in the table is the euro.
