“Let’s say that passenger A’s usual fare would be $1, passenger B’s is $5 and passenger C’s is $9. If all three share a cab (and assuming A and B are allowed to hop out on the way to C’s destination, without incurring any special fees), the total bill would be $9 — rather than the $15 they’d have to pay, total, to ride alone. How should they divide up the cost of the shared $9 ride? Or, put another way, how do they share the $6 of total savings?”
I came across this question in Emergic. There are various answers in WSJ but as registration is required to see the site, I could not access it.
What are your answers (apart from those mentioned in Emergic) ?

I feel that they should proportionately pay $5.4, $3 and $0.6. This is directly based on ratio and proportion.

Thanks for the answer!
22 December 2005, 6:07 pmNeedless to say, you are right. And given our tech (read math) background we would approach it that way. Infact all the people I sent/asked did the same.
I am curious to know what is in WSJ, so I am hoping that someone comes across this post and gives me what is in WSJ (no, bugmenot didn’t work). And am also hoping that some commenter gives me a different answer than the ones we know!
