Answer:
105 points
Explanation:
70= 40%
So, 7 points would be equal to 4% of the winning score.
And 140 points would be 80% of the winning score
to reach the winning score, we need another 20%
and since 4% is 7 points, then 20% is 35 points.
35 + 140 = 175 points
Remember, thats the full winning score
so 175 - 70= 105 points
