So I am not sure if I am even allowed to post something like this hear but I need to figure it out because it is bugging me.

Roommate 1 owes roommate 2 $12.50
Roommate 2 owes roommate 1 $7.67
Roommate 3 and 4 owe roommate 1 $7.76
Roommate 3 and 4 gave roommate 2 both of their $7.67 and roommate 2 is supposed to pay roommate one the difference.

So how much does roommate 2 owe roommate 1??

So far I've come up with $10.51 because multiplied $7.67 x 3 and subtracted 12.50 and that is how my roommate came up with their answer too but that just seems off to me.

Am I right or do I subtract $7.67 by $12.50 first?
