Answer:
23 games.
Explanation:
According to the graph, there are 17 whistles, where each whistle counts as 2 games.
17 * 2 = 34 games in Kylie's first 6 months.
She worked a total of 45 games in the entire year.
45 - 34 = 11 games.
Therefore, Kylie worked 11 games for the rest of the year.
They are asking how many MORE games did she work in the first 6 months than she did during the rest of the year.
34(first 6 months) - 11(rest of the year) = 23 games more.
