How about my nephew traveling with my friends?

My nephew followed me and my friends to travel. The best way is to split the cost equally. You can pay by yourself first, and then calculate the general ledger payment after swimming. You can also budget the cost of this trip first, and each person will give it to one person for safekeeping. After the tour, you can calculate the general ledger, refund more and make up less, which is harmonious and happy.
