Total points scored in 2 games by Sue = 35
Let the number of points Sue scored in 1st game = X
The number of points scored by Sue in 2nd game = 6X
So
X+6X=35
7X=35
X=5
Then
Points scored in 1st game by Sue = 5
Points scored by Sue in second game = 6*5
= 30
The number of points Sue scored more in the second game = 30-5
= 25
