My sister and I spent $1346 in total. I contributed $733 and she contributed $613. How much does she owe me so that we would have contributed equal amounts, $60 or $130?

Answer 1

She would have to give you $60. That would mean that she contributed $613 + 60 = $673. If she gives you the $60, then the amount you already contributed would be reduced by $60 (or $733-60 = $673).

In the end, you both would have contributed $673.
