For a party 10 friends are buying 100 cups, 100 plates a punch bowl and 200 balloons. If the friends share th cost equally how much should each friend contribute?
They should each contribute 10%. So each friend would essentially pay for 10 cups, 10 playes, 1/10 of punch, and 20 ballons. Without telling me the prices of these items I can't tell you any specifics.
