This is the part that can be solved. Well the price per match will be bigger.
On mine Manager level (15) i can get maximum price from the cup 113,02 M.
So this is what should we do
(100%-80%)/6 = Price from 1 match (First Group Stage) = 3,76 M
(100%-85%)/3 = Price from 1 match (Second Group Stage) = 5,65 M
(100%-90%)/1 = Price from 1/8 Finals = 11,30 M
(100%-87%)/1 = Price from 1/4 Finals = 14,69 M
(100%-85%)/1 = Price from 1/2 Finals = 16,95 M
(100%-83%)/1 = Price from The Finals = 19,21 M
(100%-90%)/1 = Price for the winner = 11,30 M
(100%-95%)/1 = Price for the 2nd place = 5,65 M
(100%-95%)/1 = Price from the match for 3rd place = 5,65 M
(100%-97,5%)/1 = Price for the 3rd place = 2,82 M
(100%-99%)/1 = Price for the 4th place = 1,13 M
This should be the prices for Level 15.
