To offset the annual fee is to deduct your annual fee once before, 80 yuan, but you meet the annual fee reduction policy, so I will give you a 80 yuan. The original consumption you recorded was 247. 16. If 80 yuan is subtracted, the balance will be 167.6438+06 yuan. But you have a consumption in 50 yuan that has not been recorded, so the available amount is 7783 yuan. When your consumption in 50 yuan arrives tomorrow, the balance plus your available limit is the credit limit.

If the balance is positive, you are in debt; if it is negative, you have overpaid.
