Suppose that Avery gets a credit card in November, $2023.$ She spends $$4,300$ every month on the card, just as she had done with cash and always pays her statement balance in full. She closes the card in October $2025$ and makes her final payment in November $2025.$ If she is abie to earn $8\mathrm{.}6\%$ interest $($compounded annually$)$ in the stock market, how much extra money can she save by using this credit card instead of cash? For simplicity, assume that she faces no capital gains taxes and invests in stocks that offer no dividends.
