18 points scored for a pair was 40 % of the final score
then final score is 100%
therefore if 40 % accounts for 18 points
100 % = 18 / 40% *100%
= 45 points is the final score
if we back calculate = 18 /45 *100 = 40%
Therefore the final score is 45 points

X²-2x=x
x^2-2x-x=0
x^2-3x=0
x^2=3x
x(x-3)
x=3 x=0
