Sure, let's calculate both the change in GDP per capita and the percentage change.
1. Firstly, we need to calculate the change in GDP per capita. This can be accomplished by subtracting the older GDP value from the newer one.
So, if the old GDP per capita value was 650,000 and the new value is 680,000, we subtract the old amount from the new amount:
680,000 - 650,000 = 30,000
So, the change in GDP per capita is 30,000.
2. Now, to get the percentage change in GDP per capita, we'll need to divide the change in GDP per capita by the old GDP per capita value and then multiply by 100 (to convert it to a percentage).
To do this, we take our change in GDP per capita (30,000) and divide it by our old GDP per capita (650,000).
30,000 / 650,000 = 0.04615384615384616
Taking this result and multiplying by 100 gives us the percentage:
0.04615384615384616 * 100 = 4.615384615384616
So, the percentage change in GDP per capita is approximately 4.62%.
These calculations demonstrate that the GDP per capita has increased by 30,000 and this represents an increase of about 4.62%.
