A certain volleyball team played seven games and scored an average of 80 points per game. If, in the team’s first five games, it scored 72, 65, 71, 70, and 83 points, what was the average (arithmetic mean) number of points scored over the last two games? Choices
A) 65	B) 81	C) 82	D) 119.5	E) Cannot be determined from the information given.
Avg points for total of 7 games = 80   So A+B+C+119.5+E+F+G/7=80   and A+B+C+119.5+E+F+G = 560   Given A+B+C+119.5+E = 321   So F+G = 239   So average (arithmetic mean) number of points scored over the last two games is  239/2=
