Final answer:
The amount of imports under completely free international trade can be calculated by subtracting the value of exports from the value of imports.
Step-by-step explanation:
The amount of imports under completely free international trade can be calculated by subtracting the value of exports from the value of imports. This can be represented as Imports - Exports.
For example, if a country's total imports are $500 and its total exports are $300, the amount of imports under completely free international trade would be $500 - $300 = $200.
Therefore, the formula to calculate the amount of imports under completely free international trade is: Imports - Exports.
