Problem
Five friends compete in a dart-throwing contest. Each one has two darts to throw at the same circular target, and each individual's score is the sum of the scores in the target regions that are hit. The scores for the target regions are the whole numbers

points, Ben 
points, Cindy 
points, Dave 
points, and Ellen 
points. Who hits the region worth
