Uncle Li borrowed 100,000 yuan to buy a truck for transportation. The annual interest rate of the loan is 5.4%, and the loan is planned to be repaid once a year. He can earn an average monthly freight income of 8,000 yuan from shipping goods. At the same time, he also has two expenses: postage is 10% of the transportation income, road maintenance fees, taxes and repairs are 20% of the transportation income, and the rest is profit. Please calculate how much money Uncle Li owes the bank after all the profits from his one-year transportation are returned to the bank?
