What did the delegates finally agree to about how much power Congress would have over tard?

The delegates at the Constitutional Convention ultimately decided to grant Congress the power to regulate trade, both interstate and with foreign nations. This compromise aimed to balance the need for a strong central government with the states' interests, allowing Congress to impose tariffs and promote economic stability while preventing states from enacting conflicting trade policies. This agreement was reflected in Article I, Section 8 of the U.S. Constitution, which outlines Congress's powers regarding commerce.
