Final answer:
The US dollar depreciated by 3.45% against the Euro when the exchange rate changed from $1.45 to $1.4 over the past year.
Step-by-step explanation:
The student has asked about the percentage change in the exchange rate of the Euro against the US dollar. It changed from $1.45 to $1.4 over the past year. To find the correct answer, we need to calculate the percentage change. The formula for percentage change is:
Percentage Change = ((New Rate - Old Rate) / Old Rate) * 100
Using the given figures:
Percentage Change = (($1.4 - $1.45) / $1.45) * 100
Percentage Change = (-0.05 / 1.45) * 100
Percentage Change = -3.45%
Since the value is negative, it indicates a depreciation. Therefore, answer (c) $ depreciated by 3.45% against Euro is CORRECT.
