Top 8 rows based on value with cost limits

I am looking to automate a process that I am using to pick dog sled teams for the Iditarod. A group of about 50 of us every year have a competition sort of like fantasy football or other sports where you pick 8 dog sled teams and you get points awarded to you based on how they place overall. Based on their current ranking, the teams cost x amount of dollars to have on your list of 8. You must remain under $100,000 total. What I started to do a few years ago is I take raw data from the Iditarod websites and I pull it into sql server and then I do some trend analysis and such. I then have a query to pull all of the current year racers and sort them by their trend calculation. I then pick out my 8 teams manually while having to ensure I stay under the 100k cap. What I am looking to do is automate that picking process so that the query will return me the top 8 teams while staying under the cap. What I don't want is for the query to give me the top 2 racers that are 90k total and then give me the bottom 6 racers that are 1500 a piece or whatever.

Here is the actual data, only 49 rows total. So, you can see their is a cost, a rank, and a trend calculation. I am thinking there has to be a way to write a query that would basically look at the sum of the trend across a group of 8 racers where the total cost is under 100k. It would likely have to do this calculation numerous times across the dataset so that it could determine which grouping of 8 has the highest trend calculation sum while maintaining the cost limit. This is obviously a trivial question and not a work related problem, but thought it would be fun to get some much bigger brains then mine working on a potential solution so I can automate my "mush madness" process :)

That's a great question. I think that is ultimately what I want answered through this query as I am just manually picking and choosing from the list right now based on that trend value and trying to stay below the 100k mark. I'm not as granular as I could be with a proper query to pull the data.
