To calculate the percent change in the euros per dollar rate from the first day of 2013 to the first day of 2014, we need to find the difference between the rates and then divide by the rate on the first day of 2013.
Let's assume the euros per dollar rate on the first day of 2013 was 1.3 and on the first day of 2014 was 1.4.
First, find the difference in the rates: 1.4 - 1.3 = 0.1
Next, divide the difference by the rate on the first day of 2013: 0.1 / 1.3 = 0.0769
To convert this to a percentage, multiply by 100: 0.0769 * 100 = 7.69%
Therefore, the percent change in the euros per dollar rate from the first day of 2013 to the first day of 2014 is approximately 7.7%.
