Points required to win the trophy =500
Points Kristen already scored = 418
Let Kristen require x points to win the trophy.
So making an equation using the information we have,
[tex] 418 + x =500 [/tex]
Now we have to solve this equation to get the value of x .
subtracting 418 from 500 , we have,
[tex] x=500-418 [/tex]
x=82
So Kristen require at least 82 points to win the trophy.
