Final answer:
During the 1920s, the number of bank failures varied. In 1929, about 659 banks failed, increasing to 1,350 in 1930 and over 9,000 by 1933.
Step-by-step explanation:
The number of banks that failed each year during the 1920s, also known as the Great Depression, varied. In 1929, about 659 banks failed. In 1930, the number increased to 1,350, and by 1933, over 9,000 banks had closed their doors. The economic downturn, stock market crash, and lack of banking regulations were the main factors contributing to the high number of bank failures during this period.
