parking permit fee

There are four people to share the fee $1205.
After consideration, me, Bi, and Ella count one, and Chi counts the half.
So, me: Bi: Ella: Chi= 2:2:2:1

1205/7= 172
172*2=344

Final conclusion is that

Bi and Ella give me $344
Chi gives me $172

Let me know if you have any concern~
