To calculate Macro Country's real GDP in 2023 using 2022 as the base year, we need to use the price from the base year (2022) to evaluate the output from 2023.
- Identify the production quantity in 2023: 7,000 units.
- Identify the price in the base year (2022): $2 per unit.
Now, we can calculate the real GDP for 2023:
\[ \text{Real GDP in 2023} = \text{Quantity produced in 2023} \times \text{Price in base year (2022)} \]
\[ \text{Real GDP in 2023} = 7,000 \text{ units} \times 2 \text{ dollars/unit} \]
\[ \text{Real GDP in 2023} = 14,000 \text{ dollars} \]
Thus, Macro Country's real GDP in 2023 is $14,000.
So the correct response is: $14,000.
