The percentage increase in real GDP per capita from 1980 to 1990 is calculated as:
\[
\frac{21,000 - 20,000}{20,000} \times 100 = \frac{1,000}{20,000} \times 100 = 5\%
\]
This represents the total growth over the 10-year period, not annualized. The correct answer is **B. 5.0 percent**.

To determine the percentage increase in the standard of living, we need to calculate the percentage change in real GDP per capita from 1980 to 1990.

Real GDP per capita in 1980 = $20,000
Real GDP per capita in 1990 = $21,000

Percentage change = ((1990 value - 1980 value) / 1980 value) x 100
= (($21,000 - $20,000) / $20,000) x 100
= ($1,000 / $20,000) x 100
= 0.05 x 100
= 5%

Therefore, the standard of living has increased by 5%.

The correct answer is B. 5.0 percent.

The percentage increase = (($21000 - $20000) / $20000) * 100% = (1000 / 20000) * 100% = 5%.
B
minimax To calculate the percentage increase in real GDP per capita, we use the formula:

Percentage Increase = [(New Value - Original Value) / Original Value] * 100

Plugging in the values from the question:

Percentage Increase = [($21,000 - $20,000) / $20,000] * 100
Percentage Increase = [$1,000 / $20,000] * 100
Percentage Increase = 0.05 * 100
Percentage Increase = 5.0 percent

So the correct answer is:

B. 5.0 percent.

kimi B. 5.0 percent.

To calculate the percentage increase in real GDP per capita from 1980 to 1990, you can use the following formula:

Percentage Increase = [(Final Value - Initial Value) / Initial Value] * 100

Plugging in the values:

Percentage Increase = [(21000 - 20000) / 20000] * 100
Percentage Increase = [1000 / 20000] * 100
Percentage Increase = 0.05 * 100
Percentage Increase = 5.0 percent

So, the standard of living has increased by 5.0 percent.

Explanation:
To calculate the percentage change in real GDP per capita, we use the following formula:

Percentage Change = ((New Value - Old Value) / Old Value) * 100

In this case, the new value is $21000 and the old value is $20000. Plugging these into the formula, we get:

Percentage Change = (($21000 - $20000) / $20000) * 100
= ($1000 / $20000) * 100
= 0.05 * 100
= 5.0 percent

Therefore, the standard of living has increased by 5.0 percent.

zhipu To determine the percentage increase in real GDP per capita, we use the formula for percentage change:

\[ \text{Percentage Change} = \left( \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \right) \times 100 \]

Plugging in the given values:

\[ \text{Percentage Change} = \left( \frac{21000 - 20000}{20000} \right) \times 100 \]

\[ \text{Percentage Change} = \left( \frac{1000}{20000} \right) \times 100 \]

\[ \text{Percentage Change} = 0.05 \times 100 \]

\[ \text{Percentage Change} = 5 \]

So, the standard of living has increased by 5.0 percent.
