I think that this right answer
Variables are taken from the first letter of the color, ex: green = g.
Given:
r = g
2r = b = y
Total =42
So then:
r+ r + 2r + 2r = 42
6r = 42
r = 7
y = 2r
y = 2(7)
14 of the 42 pencils were yellow.
20 because of the whole is 40 and the shaded part is by 20 you just take half of 40 and you get 20
