| 金声玉亮2.0 | C. 50 percent. Explanation: Economic growth is typically measured as the percentage change in real GDP per capita over a period of time. In this case, the real GDP per capita increased from $10,000 in 1990 to $15,000 in 2000, which is an increase of $5,000. To find the percentage change, we can use the formula: Percentage change = (New value - Old value) / Old value x 100 Plugging in the numbers, we get: Percentage change = ($15,000 - $10,000) / $10,000 x 100 = $5,000 / $10,000 x 100 = 0.5 x 100 = 50% Therefore, the amount of economic growth is 50%. |

| deepseekr1 | The question asks for the amount of economic growth when real GDP per capita increases from $10,000 in 1990 to $15,000 in 2000. The key is to determine whether the question refers to **total growth** over the period or the **annualized growth rate**. 1. **Total Growth Calculation**: The percentage increase from $10,000 to $15,000 is: \[ \frac{15,000 - 10,000}{10,000} \times 100 = 50\%. \] This matches **option C** and reflects the total growth over the decade. 2. **Annualized Growth Rate**: Using the compound growth formula: \[ 15,000 = 10,000 \times (1 + r)^{10}, \] solving for \( r \) gives approximately **4.13%** annually. However, this value is not listed among the options. Options B (5%) and D (3.3%) are approximations but do not align with the precise calculation. 3. **Interpretation of the Question**: The phrasing "amount of economic growth" is ambiguous. In economics, growth rates are typically annualized, but the inclusion of **50% (option C)** suggests the question may intend to test **total growth** rather than the annual rate. Given the options provided, **50%** is the most direct and logical answer for the total growth over the period. **Answer: C** |

| llama3.1-405B-Instruct | C. 50 percent. Reasoning: To calculate the amount of economic growth, we need to find the percentage change in real GDP per capita from 1990 to 2000. Percentage change = ((New value - Old value) / Old value) * 100 = ((15000 - 10000) / 10000) * 100 = (5000 / 10000) * 100 = 0.5 * 100 = 50% Therefore, the amount of economic growth is 50%. Note: The other options are incorrect because: A. 0.5 percent is the decimal equivalent of 50%, not the percentage itself. B. 5.0 percent is a much lower growth rate than the actual 50%. D. 3.3 percent is not related to the calculation of percentage change in this scenario. This question requires the application of basic mathematical concepts, such as percentage change, to understand economic growth, which is a fundamental concept in macroeconomics. It tests the ability to analyze and interpret data, a crucial skill in economics. |

| minimax | To calculate the economic growth from 1990 to 2000, we can use the following formula: Economic Growth = [(Real GDP in 2000 - Real GDP in 1990) / Real GDP in 1990] * 100 Plugging in the values from the question: Economic Growth = [($15000 - $10000) / $10000] * 100 Economic Growth = [$5000 / $10000] * 100 Economic Growth = 0.5 * 100 Economic Growth = 50 percent So the correct answer is: C. 50 percent. |

| kimi | To calculate the percentage of economic growth, you can use the following formula: \[ \text{Percentage Growth} = \left(\frac{\text{New Value} - \text{Old Value}}{\text{Old Value}}\right) \times 100 \] In this case, the old value is the real GDP per capita in 1990 ($10,000) and the new value is the real GDP per capita in 2000 ($15,000). \[ \text{Percentage Growth} = \left(\frac{15000 - 10000}{10000}\right) \times 100 \] \[ \text{Percentage Growth} = \left(\frac{5000}{10000}\right) \times 100 \] \[ \text{Percentage Growth} = 0.5 \times 100 \] \[ \text{Percentage Growth} = 50\% \] So the correct answer is: C. 50 percent. |

| wenxinyiyan | C. 50 percent. Explanation: Economic growth is measured as the percentage change in real GDP per capita over time. The formula for calculating percentage change is: Percentage Change = ((New Value - Old Value) / Old Value) * 100 In this case, the old value (real GDP per capita in 1990) is $10000 and the new value (real GDP per capita in 2000) is $15000. Plugging these values into the formula, we get: Percentage Change = (($15000 - $10000) / $10000) * 100 = ($5000 / $10000) * 100 = 0.5 * 100 = 50 percent Therefore, the amount of economic growth from 1990 to 2000 is 50 percent. |

| zhipu | To determine the amount of economic growth, we need to calculate the percentage increase in real GDP per capita from 1990 to 2000. The formula for percentage increase is: \[ \text{Percentage Increase} = \left( \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \right) \times 100 \] Here, the Old Value (1990) is $10,000 and the New Value (2000) is $15,000. \[ \text{Percentage Increase} = \left( \frac{15000 - 10000}{10000} \right) \times 100 \] \[ \text{Percentage Increase} = \left( \frac{5000}{10000} \right) \times 100 \] \[ \text{Percentage Increase} = 0.5 \times 100 \] \[ \text{Percentage Increase} = 50 \] So, the amount of economic growth is 50 percent. Answer: C. 50 percent. |
