I went on holiday with my girlfriend and we both paid for a variety of costs during the trip. Now that we are home, we are having difficulty working out who owes who what...
Before the trip, Girl 2 deposited €1879 into Girl 1's bank account. Girl 1 gave Girl 2 €537.50 of that money so that she would have cash to spend on herself during the trip.
During the trip, Girl 1 paid: €2,222 worth of shared expenses towards the trip. Girl 2 paid: €444 worth of shared expenses towards the trip.
If they want to split all shared expenses - who owes who money and how much?
