Last year: The nominal exchange rate was 0.60 red/blue.
This year: The nominal exchange rate is 0.50 red/blue.
Therefore, the percentage change in Blueland's nominal exchange rate from last year to this year is approximately -16.7%.
Step-by-step explanation:
To calculate Blueland's nominal exchange rate with Redland, we need to divide the value of Redland's currency (red) by the value of Blueland's currency (blue).
Last year: The nominal exchange rate was 0.60 red/blue.
This year: The nominal exchange rate is 0.50 red/blue.
To calculate the percentage change in Blueland's nominal exchange rate from last year to this year, we can use the following formula:
Percentage change = ((New Value - Old Value) / Old Value) * 100
Percentage change = ((0.50 - 0.60) / 0.60) * 100
Percentage change = (-0.10 / 0.60) * 100
Percentage change ≈ -16.7%
Therefore, the percentage change in Blueland's nominal exchange rate from last year to this year is approximately -16.7%.
