    Basic math problem

    I'm going on a trip with my friend. He put both airfares on his card (total: $260); I paid car rental on mine (total: $120) He claims I owe him $140 because 260-120=140. I think I owe him $70 because:

    I owe him $130 for airfare (1/2 of 260); he owes me $60 for car rental (1/2 of $120). So, 130-60=70. Who's right???

    Total expenses were 120+260 = 380.

    Fair share is half, 190.

    You paid 120, he paid 260 ... you owe him 70.

    Equivalently, he paid 260-120= 140 (his calculation) more than you did. But you are splitting all costs 50-50 so you owe him 140/2= 70.
