Question

A star basketball player averaged (mean) 9.4 rebounds per game over the first 20 games of the season. By the end of the 32-game season, the player averaged 10.5 rebounds per game.

How many rebounds per game did the player average over the last 12 games of the season?


11.6


12.3


13.4


19.9

Answer 1

Total rebounds first 20 games = 20 × 9.4 = 188.
Total rebounds for 32 games = 32 × 10.5 = 336.
Rebounds in last 12 games = 336 − 188 = 148.
Average over last 12 games = 148 ÷ 12 ≈ 12.3.

Answer: 12.3.
