Hannah scored 312 points during the basketball season. If her average (mean) was 13 points per game, how many games did she play?
(A) 24
(B) 41
(C) 17
(D) 13
(E) 30
The average (mean) number of points scored per game multiplied by the number of games played is equal to the total number of points scored during the season.

Therefore, the number of games that Hannah played is equal to the total number of points she scored during the season divided by her average (mean) number of points scored per game, or $312 \div 13=24$.

ANSWER: (A)
