Answer: d. No; Janet could not have won 10 games because 3x ≠ 24.
Explanation:
Assume the number of games won by Janet is x. This would mean that the number of games won by Nadia is 2x.
The total number of games played by both would therefore be;
x + 2x = 3x
Janet has won 10 games and we need to find out if the total number of games can be 24 if this is the case.
Expression would therefore be;
3x = 24
x = 10 so;
3(10) ≠ 24
There is therefore no way that they could have played 24 games if Janet had won 10 games. They would have to have played 30 games.
