Answer:
Article I, Section 8 of the United States Constitution grants Congress the power to "coin Money, regulate the Value thereof, and of foreign Coin, and fix the Standard of Weights and Measures." It also grants Congress the power to "lay and collect Taxes, Duties, Imposts and Excises, to pay the Debts and provide for the common Defence and general Welfare of the United States."
Additionally, Article II, Section 2 of the Constitution grants the President the power to make treaties, subject to the advice and consent of the Senate. This means that the President can negotiate and sign treaties, but the Senate must approve them before they can take effect.
Overall, these provisions of the Constitution give Congress and the President the power to regulate the country's money and trade, including the ability to mint coins, set the value of currency, levy import duties, and make treaties with other countries.
