Take the existing handling fee and interest. The handling fee is charged at 1% of the withdrawal amount, and 1500 is 15.

Cash withdrawal (cash advance) has no interest-free period, and interest is charged for as many days as possible, which is five ten thousandths of the cash withdrawal amount every day. Withdraw cash 1.500 yuan, with daily interest of 0.75 yuan until it is paid off, and pay off after 30 days: handling fee+interest totals 37.5 yuan.

Repayment is required after one month 1500+37.5= 1537.5 yuan.
