Gem and Jwill, the amount you are giving is the total of your league fees each week. Those fees are broken down to lineage, prize fund and to pay the secretary/treasure. Lineage portion is what is paid to the center for use of the lanes, the prize fund portion goes to the prize fund for the pay off at the end of the season and the sec/treas. portion is to pay that officer(s) for doing that job. This should be found in a copy of the league rules that are handed out to at least the team captain of every team.
For example, my league fees are $20 a week. Of that $20, $10.35 is for lineage, 25 cents pays the sec/treasure and the remaining $9.40 goes to the prize fund.
I think my lineage is $10.35 anyways, it might be more, I know it went up this season but can't remember the exact number. This is one of many centers in my area but the only one I bowl in right now. I'm sure it's in line with most of the other centers since last time I bowled in another center it was had similar lineage fees.
