In 13 games she has an average of 14.
Average = Total goals / no. Of games
Therefore, total goals scored in 13 games till now =
13 * 14 = 182.
To do better than last year, her average has to be at least
19 from 15 games.
I.E. She has to score a total of at least
19 * 15 = 285 goals.
She has scored 182 goals in 13 games till now.
So in the remaining 2 games, she has to score
285 - 182 = 103 goals.
This is highly unlikely.
Hope you got it :)
