3. Pearl wants to determine the average
number of goals she scored her first five
field hockey games of the season. She
scored 2 goals in the first game, 3 goals
in the second, and 5 goals in the third.
She can't remember how many goals she
scored in the fourth and fifth games but
she does remember that she scored the
same number of times in each of those
games. The expression
2 + 3 + 5 + x + x
will determine the average number of
goals she scored, where x is the number of
goals she scored in each of the fourth and
fifth games.
If Pearl scored 2 goals in each of the
fourth and fifth games, what was her
average number of goals per game?
