The credit card interest of ABC is calculated at the daily interest rate of 0.5 ‰, compounded monthly and deducted from the cardholder's account. Under normal circumstances, ABC will only charge interest if the cardholder fails to repay, withdraws cash by credit card or only pays the minimum repayment amount. Assume that the cardholder's overdue repayment amount is RMB 6,543,800+0,000, and 5 yuan interest will be generated every day.
