I believe it is B, because going down would be negative, and it is subtracting 6.
61.
40 ==> 100 %
x ==> 15 %
15*40/100 = 6.
Therefore, merely 6 students received C grades.
62.
23 500 ==> 100%
x ==> 42 %
42*23500/100 = 9870
Therefore 9870 people in the town are over 45 years of age.
You continue wth this method and you'll find for the 63, 64, 65.
In maths, you have to understand what you're doing dude ^^.
Whatever the answer for 64 and 65 are
64.
21.50*20/100 = 4.3
65.
250 ==> 100 %
45 ==> x %
x = 45*100/250 = 18 %
i will let you do the 63 alone, give me what you have found in the comments, i'll verify your answer.
Hope this helps !

First we move 6y to the other side. To do this, you subtract 6y on both sides
C
- 6y = 8.5x + 6y -
6yC - 6y = 8.5x
No divide both sides by 8.5 to isolate x
