To find out how many rubber balls Dylan should give to each game, you can divide the total number of rubber balls by the number of games.
Dylan has 1,256 rubber balls and there are 13 games.
\[ \text{Number of balls per game} = \frac{1256}{13} \approx 96.77 \]
Since it's not practical to give a fraction of a ball, you can round this number.
Looking at the options provided (60, 80, 100, 120), the closest whole number is 100.
Thus, Dylan should give about 100 rubber balls to each game.
