Alan, Bob and Chuck own an advertising firm. The profit is allocated as follows: Each partner received $80,000. Any remaining profit is allocated in proportion to the revenue over $2,000,000 the partner brought in. Alan brought in $2,200,000 in advertising revenue, Bob $1,900,000 and Chuck $2,350,000. If Alan's share is $108,000, how much is Chuck's share?

Answer given is $129,000

Only Alan and Chuck brought in over 2,000,000.

Alan made an extra 200K
Chuck made an extra 350K
So, Alan's share is 200/550 = 4/11
Chuck's share is 350/550 = 7/11

So, Chuck's share is 7/4 of Alan's, or
7/4 * 108K = 189K

Hmmm. Better check to analyze my method.
