Question

how would a nation most likely try to limit inexpensive cars from being imported?
by imposing sanctions against the country where the cars are made
by imposing tariffs on the cars at the border
by entering into a free trade agreement such as nafta
by withholding aid from the country where the cars are made

Explanation:

Tariffs are taxes on imported goods. By imposing tariffs on the cars at the border, the nation makes the inexpensive cars more costly. This discourages imports as the price advantage of the foreign - made cars is reduced. Sanctions are broader economic penalties (not specifically for imports), free - trade agreements promote trade (not limit it), and withholding aid is a different form of foreign policy action not directly related to limiting imports.

Answer:

by imposing tariffs on the cars at the border
