There are 6 players on a coed volleyball team. After a game, each girl drank 5 cups of water, and each boy drank 7 cups. The coach drank 9 cups, and 43 cups were consumed in all. How many girls and how many boys are on the team.

Answer:

2 boys, 4 girls ....... Let x = the number of boys and (6 - x) = the number of girls. The boys and girls drank 34 cups together (43 - 9) ........ 7x + 5(6 - x) = 34
