Answer:
Increasing the price of foreign goods.
Step-by-step explanation:
A tariff is a tax on an imported good. Tariffs have been used throughout American history as a means to protect American industries. This is due to the fact that the tariff increases the price of foreign goods. This is supposed to help American businesses, as it makes their goods cheaper in comparison to foreign goods. This is because American businesses do not have to pay tariffs since the goods are made in the US.
