Final answer:
The delegates took significant actions regarding money by creating the National Banking Act to establish a national banking system and uniform currency. More recently, debates over the federal budget led to raising the debt ceiling and spending cuts through the Budget Control Act of 2011.
Step-by-step explanation:
One key action that delegates took about money, specifically detailed within the context of U.S. history, was the creation and approval of the National Banking Act, which established a national banking system and a uniform national currency. This act was a response to the financial needs during the Civil War and was aimed at creating a stable and secure currency and supporting the war effort by issuing government bonds. Additionally, in more recent times, Congress and the President have engaged in intense debates over the federal budget, with significant actions such as raising the debt ceiling and implementing spending cuts through legislations like the Budget Control Act of 2011.
