.
x=number of games in fourth week
y=number of games in fifth week
Average games per week = 6
.
Average games per week=Total sum of games/number of weeks
6 games/wk=(4 games +7 games +5 games + x + y)/5 weeks
30 games=16 games + x + y
14 games=x + y
14 games - x=y
.
ANSWER: Since only three weeks of games were given,
the number of games played the fifth week to average
6 games per week would be 14 games minus the number of
games played the fourth week.
