Big Water's Edge 2007 Tournament

[Jim Sammons LJKF]

Entry Fee: $40

Optional Jackpot: $20
Payout: 1st place- 50%, 2nd place- 30%, 3rd place- 20%
A portion of the entry will benefit Hubb's White Seabass Program

Can you clarify this for me.
Is the payout from the Entry, optional Jackpot, both combined or other.
Payout covers 100% so what portion is going to Hubb's
It says optional jackpot is that paid out by percentages or is that all going to the one biggest fish.

Thanks for the clarification
