Tongtong's family is going to buy a 100m**2 commercial house. If the mortgage payment is to be increased by 5%, if the one-time payment is made, they can enjoy a "5% discount" discount. Tongtong calculated and found that the mortgage payment was 36,000 yuan more than the one-time payment. Do you know how much the original price of the house was?
